Toyota Idle Air Control Valve Maintenance (Correct Idle & Cold Start Issues) | AnthonyJ350

- Опубліковано 27 чер 2024
- Our 1993 Camry with the 2.2L 4cyl 5S-FE motor was having surging issues at low speed during acceleration and would sometimes be hard to start up in cold weather. We isolated the problem to Idle Air Control Valve. But you don't have to replace it, you can clean it!
Symptoms like this, one might think it could be the ignition, fuel filter or poor starting possibly the battery or starter motor. The idle air control valve is a very easy to over look item that needs attention from time to time.

You saved my car! Totally fixed my wife's car. I was about to buy her a new car and you saved me! I love you forever... Lol..
Glad to hear this helped!
AnthonyJ350 hey was your Camry cutting off while you was driving or slowing down and was your check engine light on????
Clarence Nash I have this issue now. It happens at a low speed, like when o stop at a light, or slow down. It went off at a light. Also, after it has almost shut the car off after I’ve slowed, when I try to accelerate, the gas peddle feel stuck, like it’s blocked or something. So I keep pressing it slightly, and then suddenly it feels soft again and the car is able to accelerate.
Have a 1999 Ford F150 when you drive it. Rib-eye Glen I need to shut off when you're not rubbing it I need backfiring when you press regressed
Im pretty sure your wife hates him lmao
I, purchased a new idle control assembly from parts geek online. 96 Toyota celica ST 1.8L, 46.00 Dollars! Also replaced the complete fuel rack with injectors for 87.00 dollars & replaced fuel pump 25.00 dollars. Replaced timing belt & plug wires & plugs & new distributor assembly for 95.00 dollars on Ebay. Purchased the vehicle for five hundred dollars. Towed home did a really good tune up on it. Running like a champ! Excellent video on servicing the idle control valve. Great information thank you!
Thanks for sharing, hope the car gives you a bunch of reliable years of service!
I want to say thank you for this vid, mine was rock solid still and took quite a bit of persuasion but after said and done i have now literally doubled my economy and it idles 400rpm lower now to where it should be, thank you sir.
Glad it worked for you!
Great video and very good information. I had a similar problem with my 1982 Toyota Corolla and this video has made me understand what I need to check. Anthony J350 thank you.
Thanks for watching!
"I bought a 94' Celica for $350.00 and fully restored it". Great video! Scotty Kilmer
Thanks for watching!
Definately fixed rough idle on my 1996 camry that I got for free. Car had been sitting previous owner had it sitting with old ethanol. Cleaned it out based off this video and instant fix. The junk I cleaned out was horrible
Glad to hear it helped!
Another good tip is when you’re cleaning your throttle body, spray into rag…if you spray directly on butterfly, all the carbon buildup will go down in the hole to the IAC valve and clog it up. If this happens, same thing, don’t spray directly into IAC, clean it with q tips soaked in cleaner. I say this from experience😅
Ps, if you are going to clean it and spray it directly, take it off and turn it upside down
Thanks for the tip!
Helpful. Thank you. I have a 96 wagon with the 2.2L with similar issues. I will remove the IACV and clean it and see
Let us know if it helps out.
My 2 litre 1998 Rav4 was stalling instantly on cold start....I'd cleaned this before and it wasn't really dirty but it instantly fixed the car,sitting at around 1100 rpm on cold start....it's not used that much,I think it was just a bit sticky due to lack of use.Nice easy fix.
Thanks so much for sharing your experience! Really helps others.
Great video! One important thing to notice is there is a small amount of silicone adhesive between the two thus Toyota considers both the electrical and the mechanical sections as one complete piece. If you continue to have problems at idle, consider adding fresh layer of silicone to the one of the matting surfaces an waiting until it has cured. Best of luck everyone
Thanks for sharing!
very good job my Toyota have the same problem I do it by watching you
Did it work out for you?
Good job Dude , Now after watching this video I am doing it next week with my Camy 2001.u got one more subscriber
Thanks! If that doesn't work the problem might be related to the EGR.
@@AnthonyJ350 Yes , I did this,Engine runs very smooth .Will see how it goes after driving couple of hundred miles. EGR valve I tried to open up to clean it ,but one of bolt broke inside the body .I need to go to the mechanic now .(I guess).Thanks AnthonyJ350
Thanks for the help. I did this to a 1999 toyota avalon. But you forgot to mention that you have to use an RTV sealant that is gas and chemical proof. 1st time I did this it worked for a while then acted up again. Used the right gasket sealer and working fine. Also u can test the resistance and make sure it's within tolerance. Thanks again and happy holidays. God bless.
Thanks for the tip!
Great video mechanics like to over price stuff thank God for these videos

I️ own a 98 Camry 2.2L and it always dies from a cold start, in the morning or when the engine is cooled down all the way. I️ have to hold the gas and keep the idle stable myself until the engine is warmed up before I️ can move it. I️ was wondering for weeks what the problem was but now I️ know, this video is highly appreciated.

This is helpful, I have an '88 Camry inline 4 and it has a hard time starting too (all tune ups done and new distributor/filters). Then today it was surging up and down in traffic after a one hour highway drive. Runs fine otherwise.
Let us know if this helps.
If it’s a 88 it might be carbureted engine, same with my ‘90 Corolla, with cold starts you have to press the gas pedal a couple times before you start it.
@@nachos4018 Thank you. No, she's an EFI system with a cold start injector.

Hi Anthony. Thank you for this info. Very helpful.
I just want to ask, do you have video tutorial how to return cold start setup?
My car has below 800rpm during cold start and goes to 1000+ rpm when it heats up. Appreciate your reply. Thank you
No I don't have a video for that. You can take off the negative battery terminal, push the horn to discharge the caps in the computer and let it sit overnight. Hopefully that resets the factory computer.
Hi, always come back here to see how to do it properly. Thanks for this!
Gonna ask, if do you know what color and order your socket has? I don't have a socket on my IACV, had to insert the wirings one by one. I tried the black on the far left or the last pin down, red in the middle and green on the right or the pin on the top.
And lastly, I think I screwed up the little cylinder on the middle of when you remove the solenoid, I tried moving it left and far right. And now our car idles on cold start at 1,300 and idles at 1,100. -_-
We have a 97 3sfe toyota corona exsior
It should only plug in one way
You think that could be my problem?? I have a 1992 Toyota Celica GTS with the 2.2 motor problem is mostly of the time it kinda bogs down for like a couple of seconds while accelerating, also theidle is always at 1000rpm sometimes jumping back and forth to 1200rpm , thanks for your time and help God bless you 🙏!!!
Maybe it is
Corolla 02. Hesitation when hot. Changed spark plugs and coils , Maf sensor too. Can I adjust idle speed screw? When Ac is on no hesitation. Also changing my injectors tomorrow. I'll go from there. Thank you very much!
Thanks for watching!
Awesome fix Anthony, I'm having a similar issue when I start it cold. However I noticed there is motor oil coming into the air intake hose from the small hose on the side, is that normal or how much should I worry? Thanks man
That hose is part of the PCV system. It's normal for a little oil to pass through. Here's a video
ua-cam.com/video/DJ7Z2F51fzs/v-deo.html
Same engine as my 94 celica going to give this a go having a similar issue
EGR valve could also cause the issue. Look into an EGR delete
I’m able to drive for a good 20 minutes down the road then my car starts acting up rpm gage acting weird. I’ll look into it thanks
@@seanramos8166 did you ever figure it out?
HeartofTacoma I did! My celica is my daily driver now! I had a performance air filter I replaced the original air box with.. there was a sensor connected to the original box that I just let hang, it drove for awhile then started actin up and eventually stopped working. I put the original air box back connected the sensor to it runs great now.
1995 camry rough idle, didn't go away with this. I replaced the blue VSV solenoid on the side of the block, called dealer for part number, bought it on E-bay, works fine...kind of a pain to remove and replace....
can u make a video or a walkthrough if u don't wanna do the job again and post a parts/AMZN link for the part?!
@@byb-bangforyourbuck2353 Vacuum Switch Valve, or VSV toyota part # 2586074050-121 bought it on E-Bay. It is bolted on to the side of the block, behind the power steering pump, between the engine and the firewall. VSV has a blue electrical connector. You have to remove the passenger tire, remove a plastic inspection cover fastened to the fender well, to get to this valve. Not easy to get to, not easy to remove and replace. Will try to make a video.
Thanks for sharing!
You should put a kind of "coldstart problem" in the main tittle .... it would help for the search .... i've been had the same problem this week with my 2001 echo and this video would had made me save hundreds of dollars if i had coulded seen it before
Thanks for the feedback!
I got a 1996 Corolla that idles high on Park, to the point that the dashboard vibrates. When on Drive the idling goes down, but some vibration is still there. I’ll do what you recommend to see if it fixes it! It’s got 233K and it’s my daily driver!
Did it help?
I have the same thing happening, but I think it’s more likely the motor mounts
Looks easier than a 91 Honda accord. As far as the cleaning goes. I've got a V6 99 wondering if it's the same
Let us know!
If anyone is looking to replace their Idle Air Control Valve
www.rockauto.com/en/catalog/toyota,1993,camry,2.2l+l4,1273306,fuel+&+air,idle+air+control+(iac)+valve,6072
AnthonyJ350 it is not need to change the air control valve. most of the time is only carbon build-up. Now a day ,the cleaning product are v good.
Recommendation: do not spray into the valve with the vacuum line on. I heard it runs into the crank case and that is bad. Instead, remove the vacuum line and plug the hole with a finger (I wore nitrile gloves)
Thanks for the feedback
Live in the UK & own a 1970s Toyota. Different system back then, but with idling issues nontheless. It's an automatic & although not fitted with a rev counter should be at 1500 rpm when starting from cold, then fractionally above 1000 rpm in Park or Neutral, fractionally below 1000 rpm when in gear at full operating temperature in those cases. Instead certain times idle drops to zero when in use warmed up causing it to kill itself stopping at junctions, roundabouts & red lights. Also can tell when it's not right when it runs uneven & lumpy. Would be a good car if idle speed stayed at the mentioned constant level & permanently so.
Thanks for your comment!
I’m having a hard time taking the cover off to reach the idle air control valve how did you do it?
Thank you god bless you
You're welcome!
hello, thanks for your video, can you comment...01 RAV 4 runs great, really hard to start cold or hot. 100k miles, put new plugs in , did not help; but idle is smoother. Runs & accelerates well, but even when engine is fully warm, trying to start with a few bumps it chugs and dies. Have to really grind on the starter...thanks!
It might also be the EGR valve acting up. That was an issue for one of our Toyotas before.
Hey Anthony, I don’t know if your still responding to comments but my 97 2.2 I think has a bad iac, now I’ve been chasing my tail forever trying to figure out the problem and I feel these things are connected and I would love your help. So, quite a bit of oil gets in through my pcv and my intake has carbon buildup all over and when I take off it jerks aggressively and then smooths out in the 3,500 rpm range and up. I think it’s iac and I’ve cleaned it. It also only does it when the car has warmed up. I’ve done everything tune up and I would love it if we could maybe exchange messages so I can get some more knowledge about my vehicle because it only has 145,000 miles.
You might also want to check the EGR, it might be malfunctioning.
I have a 95 Camry. It wouldn't pass smog because it was idling at 1,100 RPM's. It doesn't surge at idle, it just runs fast. It should idle at 750 RPM's. I will give this a try.
Let us know if it helps!
@@AnthonyJ350 I just tried it and I got the RPM's down to 750-800. I take it to the smog shop tomorrow. THANKS A LOT! I'm sure it will pass now.
What's up AJ. Gotta love them Toyota's. These cars are notorious for idle issues 😥
It's noticeably breathing nicely at startup. Is it snowing in your area? Just wondering
thizzface Ya I've cleaned the throttle body before but didn't service the Idle control valve. It's seams much better now so it must have been getting stuck all this time. It's hasn't really snowed in my area. It goes to -1 Celsius at night right now.
AnthonyJ350 Noice! That's a good point. I swapped out our Camry egr a few times thinking that was the cause but symptoms just repeated. not cleaning the throttle or IACV was my fault. Great vid bro
thizzface I'm hoping it'll help out other people. I think this help the bogging I was getting at low speed.
AnthonyJ350 I couldn't agree with you more. Although it varies. This remedy applies to most vehicles including our VQs. I asked about snow if you run into issues regarding cold weather.
thizzface It seemed to be having odd start up issues when the temperature dropped. The test will be the next few days when I bring it to work and let it sit outside. An oil catch can on our Z's on the throttle side will help with this.
Good video. I have same engine -92 and one cylinder drops out when running idle and on low revs. Shakes a lot on under 3000rpm when accelerating. Have to try this because new plugs and coils and tubes did not work. I hope its not the fuel inhector. Pump probably not the issue cos engine runs fine on high revs. More hints :)?
You can try upgrading the ground wires in case it's an electrical issue.
@@AnthonyJ350I saw that suggestion on another video. When I asked 2 different mechanics about upgrading the ground wires, they seemed to be confused as if that's the first time they'd heard of that.
That camry looks like it was garaged it's whole life.
It's parked outside and used as a daily. Just really well taken care of.
Does the actuator valve reset its position automatically? Cuz when you take it apart and twist that valve it will basically just stays where you set it. There's not a spring or anything to close it. So when I took mine apart and cleaned it I didnt know exactly where to position it before putting it back together?
It's magnetic, so you just have to reinstall it.
hi sir nice to see u video....i have camry 2007 2.4 ......i have same cold start problem.......I already cleaned injectors ...throtal body ....new spark plug and also changed new fuel filter .......but still when its cold it will take minimum 3 to 4 self then start .......after start going well no idle problem no jurking .......when its hot then start easily but when its cold then take time to start ...do u have any idea to solve this isuue ....i will be very thankful to u .
I would try taking off all the grounds and cleaning them and add dielectric grease. Also clean the battery terminals and make sure the battery is in good condition.
The way to regulate the IAC valve is to turn the screw all the way down and return 6 turn CCW, rhis is the original setting.
Thanks for sharing!
Is that the original setting for this motor or it applies to all Toyota motors with a screw adjuster?
Hi, how to do that?
What exhaust do you have on this Camry? It sounds really good!
A Magnaflow 14" round muffler that replaced the factory resonator and one of their Street Tune mufflers in the back with a double walled exhaust tip.

Hows your car working now after the idle car issue ?no longer having problems with cold starts?
Cold starts are perfectly fine. It started stalling due to the EGR being faulty. Now it's all good
hi there i was figuring out for a month now what is my 1995 corolla problem doing thanks to you now i know but i preffer to buy a new part for it i will just replace it i also replace the fuel filter ,fuel pump ,fuel injectors ,spark plugs and wires and now the idle air control valve .....weeeew i wonder what's next i guess its a 28 yrs old car i never replace anything except the spark plugs and wires and oil
Let us know how the car drives after!
Having a bit of a low, semi-rough idle on my civic. How’d this work out for you?
It worked good for us
toyota 4a-fe engine in my 97 prizm. engine boggs when releasing the accelerator, braking/idling at low speeds after accelerating some. seems like that was a similar issue to yours, however i cannot keep my car in park/neutral. it revs up and down constantly. Only when you cold start the car does it idle “normally” for about 45 seconds. Then the engine drops rpms to practically stalling and then starts revving up and down. Do you think this will help with that too? Trying to fix this problem for cheap rather than buy a new IAC Valve. Car was free 🤷🏼♂️
If the car was free and original IAC valve is cheap in the grand scheme of things.
Toyota’s are like energizer bunny’s. 👍
Yup, they just keep on going!
My 2006 Toyota Sienna bogs down when I start to accelerate and is very choppy unyil it gets higher speed >30mph-ish. It revs up just fine when it's in park, but in drive is when it bogs. Could cleaning the throttle body and that little hole be the fix? Maybe it needs a new o2 sensor? Thank you for your time.
Has the van ever had a tune up. Are all thr fluids changed regularly?
Have a 2006 toyota tacoma 4cyl after cleaning TB on cold start up rpm jumps to 2000rpm has never gone that high before TB was cleaned. Idles fine after warm up how do you reset to stop high idle at start up. Thanks
Try disconnecting the negative terminal, push the horn after and let it sit for an hour to reset the computer. Hook it all back up and take it for a drive.
You can see if there's also a relearn procedure for Toyota.
Been having the exact same problem with my car as its a 98 model it kinda wanted too die today at a stop light but i nust turned the corner anyway and i heard a filthy TB and Dirty iacv can cause this did you use MAF cleaner and TB as well ??
Just cleaned the throttle body with CRC throttle body cleaner.
AnthonyJ350 how about the little square port and do I remove the electronic part as well as the middle hose underneath soo i can get access too the screw too let the gunk out and will it have a hard time starting afterwards??
Quick question, after I replaced the spark plugs, I unplugged the throttle body and clean it, now the car won’t idle. It runs smooth (not rough) for 5 seconds then turns off, do I need to reset the throttle body? Basically the car stalled after five seconds.
Try holding the throttle open a little after you start it so it can burn off the cleaner.
No cleaner was in the engine. It appears the the throttle body couldn’t stay opened for idling.
I solved the issue, a fuel pump resistor with heat sink that was mounted to the windshield wiper tray needed to be plugged back in. That explained the short running of the engine of about 5 seconds.
@@davidnguyen5028 thank you for adding the fix to your system
IAC QUESTION; Do you know if the IAC Is responsible for raising the idle speed when you turn the a/c on in an older Camry? I know the computer is involved, but does the IAC do the physical work? My 99 Camry's idle spools up a bit higher, then it settles down to exactly where it was when I press the a/c button to on. What is confusing to me is my previous 98 Corolla maintained a higher idle speed when I pressed the a/c button on to help with the bigger load on the engine. Just not sure if my Camry is supposed to be doing the same thing.
I would bring it to your local trusted mechanic to get their opinion.
@@AnthonyJ350 I appreciate the advice, but I do all my own work to my cars. I'm just inquiring about the IAC to confirm that it works differently than my last Toyota. Thanks.
My 04 corolla have high rpm when cold start( 2100 rpm) and come back down afte couple minutes when its warm. I clean the mafs sensor and throttle body but it didnt change nothing. Whats ur opinion
Maybe look into changing out the air intake temperature sensor and also check for vacuum leaks.
Hello thanks for the help.
One question, does the valve only rotates back and forth in clockwise direction, or anticlockwise too ? Thanks
Bernardo Picanco
Back and forth, so clockwise and counterclockwise....
It just goes back and forth.
Hi, great video! I have an issue with a high idle every time I start my 96 Corolla. When I put it from Park to Drive then the idling goes down. Do you think it might be the IAC?
Worth a shot and cleaning it out.
Not sure if the MAF might be involved in that issue too, very quick and easy to clean that but needs careful handling (plenty of videos). Be forewarned, I just pulled my whole throttle body out, detached the IAC bit (it's different style to this one - 2002 corolla) and cleaned everything thoroughly with throttle body cleaner, toothbrush, and cotton buds for the small crevices. Runs great now BUT it idled high (just over 2k) when I first started it up again - I knew to potentially expect this so it didn't worry me. It takes a little time for the ECU to re-learn optimal settings. I let it sit idle for few mins in Drive (went to normal), took it for a drive around the block, couple mins blast along the highway, then pulled over and idled some more - it was better already but still a little high so finally I'd read that allowing it to idle with the AC/Fan running could help. I turned the headlights on as well. All this puts a little extra load on the motor (by way of A/C and alternator pulleys) and I guess requires the ECU to use the IAC to make further idle adjustments. I saw the idle drift downwards during 4-5 mins sitting with these things on. Once I got home few mins later it was idling great at just under 800rpm. You don't have to, but but watch some videos if you do decide to pull everything apart, there are some small coolant lines that go to the IAC to help it stay warm and so you need to be prepared to plug them up as you disconnect them (old spark plugs are good). It's not a difficult job if you know what to expect but each car is different and some things were mounted differently than I'd seen in US corolla videos, so it's just time consuming if you're inexperienced. But totally doable if you have some basic tools and prepared to work methodically. Take care not to damage old stuck coolant hoses etc. If you only have a couple hours just try cleaning it like this first. Good luck.
@@chocolate_squiggle I have this video for cleaning the MAF ua-cam.com/video/iU3inRdJ0H0/v-deo.html
Could this be the same problem on a 3sfe ? I got a NO fail on my smog but i did a new gasket and spark plugs with oil change and radiator flush. Still bogs right under 2000 rpm.
Good chance of the EGR isn't working properly as well.
In my Toyota Corolla 4efe 1.3 1999 model I have a little problem with the cold start at the winter
Should I check this?
I would check it.
I have an issue where my 98 corolla idles at about 1100 when started for first time in morning then after about 20 minutes of driving goes up to between 1200 and 1800. Would it be the IAC?
You would have to hook up an OBD and live data stream it. Your car goes into a different mode when warmed up and uses the sensors to run vs preset tables when cold.
Hi Anthony my c
My Camry LE have the issue.. whenever the AC is on ,shift to D and R the rpm drop and vibrate..but without an AC it won't vibrate or Rpm won't drop..
Do you have any suggestions that how I can try to solve this issue..
Any help is appreciate Anthony
Sounds kind of normal since the compressor is adding drag to the engine. A lot of 90's vehicles are kind of like that. Is the car completely stock?
Its a completely stock..but the rpm drop is and greater than usual.. sometimes I have to switch of AC when reversing the car , with AC the engine almost death..
I suspect the IAVC or FICD..
@@aroydonnak When was the last tune up? Also can you check the voltage with the ac on and off? I would consider upgrading the grounds as well.
Ok, I'll try to tune up and upgrade my grounding...will update u again..thanks Anthony
Hi, I can see this post is 6yrs old but, where does the vacuum line under the map sensor goes to ??
I can't remember anymore, and we sold the car so I can't go check.

It's worth trying
Did you use throttle body cleaner for the electrical connector?

And I just want to ask u tht is there two hoses attach with ur idle valve sensor underneath it
Yup it has hoses attached to it.
What is the possible damage if your car Toyota Vitz 2008 got low idle and rough, vibration too much when you put into reverse and drive
You'd have to ask you mechanic to diagnose the car in person.
Hope you can help me to know the location of iac valve in toyota corolla 2010.
No idea, did you check the service manual?
Sir, I had to adjust my low idle rpm , and i fixed it by adjusting the Throttle stop screw, and it also worked. But then heard there's another screw called Idle Air Adjustment Screw, which is there specially for this purpose of adjusting idle air flow? and that the Throttle stop screw should not be changed but instead the idle air adjustment screw should be adjusted?
I'm really having this confusion which one should i be adjusting and what are the difference between.these two?
me my understanding of a throttle stop adjustment is that it limits how much throttle you can give the vehicle. The idle air adjustment is just how much air goes into the engine when at idle
What exhaust are you running. It sounds good
Magnaflow for the resonator and muffler.
@@AnthonyJ350 you think it will be cool to clean this with break cleaner? Instead of carb cleaner?
don't use thread looker on these small screws if you think it will come loose just pu washers and lock washers on them, you can't put a socket on them to remove them
Thanks for the feedback!
I have high RPM when the engine is hot, when the car is started cold everything is normal.
what could be my problem? 4E-FE engine
my temperature is always 85º+or-
Please, help me im FROM Portugal 🇵🇹
How many times did you have to spray it be because after I sprayed it it’s still doing it
If it continues to do it, you may have to replace the valve.
Did you have high rpms at park neutral
Only like 2,000 RPM
Where does the hose on that little vacuum cushion thing connect to?
Did you follow it?
My 96 Camry will be running like a kitten and then out of the blue die. Looking for any helpful hints on what to service because no one seems to know what’s happening. Thank you!
If it's not this check the EGR valve for operation.
AnthonyJ350 What’s the best way to check the EGR valve for operation? Last time it died on me I immediately pulled the throttle body boot and noticed some smoke...does that tell us anything that might be happening?
❤ Thanks for sharing.
Can this be applied to a 90 4Runner AT, V6, 4WD, 3.0 with fluctuating idling.
Should be able to, don't see why not.
does that problem turn the check engine light on and cause the car to not want to drive when in gear mine does that until it warms up and the check engine light will go off and car drives great until it it shut off again
Maybe, I would scan the vehicle when the check engine light is on to see what part of the vehicle is being affected.
Hi, How do I find the idle control valve on my 2013 Toyota Premio G Superior ?
You'll have to consult a service manual.
Does anyone know how to lower the idle speed on a 2000 Toyota Avalon? When at a stop it keeps wanting to move forward! Even on a slight incline up it creeps upward!
You'll need some sort of scan tool or programmer.
is this can apply to my problem, when i turn on AC the idle get down and shake almost off engine. thank you
No that's just strain on the engine because the compressor is engaging.
Yes iac is there to bump idle up when ac is on and smooth it out. Also increasesidle over 700rpm tomaintain charging from alternator when you turn on high drain electrical accessories and radiator fans. If your battery goes dead while idling with ac on for example...and alternator is good then its likely that the iac is not working properly. Ive also had cracked vacuum hoses cause poor or high idle
Will Doing this fix a. P0505 engine code on a 2000 Camry ?
It might, try it!
What model and year in your video?
1993 Camry
What Toyota is this for...? Or which one does this repair work for exactly...? Will it work for a (2005)~Toyota~Corolla~CE...? Or nah...?🤔😕
This was in a 1993 Camry
My 98 rav4 is idling in gear at about 550 and the thing shakes like crazy. No codes. Data seeeeems okay from a layman's look other than low rpm. Think IAC? I hate to do a parts cannon on it.
I'd also check for vacuum leaks. It's older so vacuum lines can crack over time. Also check the PCV valve.
@@AnthonyJ350 vacuum would increase the rpms no?
What is that you are using to clean
Throttle body cleaner
Damn bro i have a 1995 4runner and it started with having to replace the EGR valve then the code 31 poppee up b i clean the throttle body the connection to the mass air flow sensor n it hesitates for the rpms to go up so it slowly starts to get speed ima try thisni hope n prey it fixes the problem i do have that issue early morning it dies n after like 4 times of trying it turns on n stays on
Did you fix it?
I did this on my 2001 camry le and the idle jumps back and forth between 1 and 2. Any suggestions??
Nobody answer the phone!!!
Please Anthony!!
Did you let it dry up before driving?
I have lexus gs300 ... sometimes when I start my engine dies soon and the security light flashes and it dsnt get reset... sometimes it will take one day to reset.. why this happens
Seems like the factory Immobilizer is activating. Do you have a spare key? Try turning unlock in the driver's door before starting
Hello, I have a 2000 camry 2.2l witk 96k miles with high postive long term fuel trim at 20% at idle, short term flucuates between potisve and negative 5% , but at higher rpm the long term fuel trim drops to 5%, but I cannot find a vaccum leak visibly, would a exhaust manifold or intake manifold leak would cuase this? Or would a bad/clogged fuel injector cause this? I also have do NOT have check engine light on. Also I've replaced both 02 sensors, pcv and valvet cover gasket, cleaned throttle body, swapped spark plugs added new denso fuel pump and strainer.
Try running a good fuel injection cleaner like Lucas and also try upgrading the grounds for the battery and engine.
@@AnthonyJ350 I also swapped the fuel filter and swapped out to a different oem MAP sensor. Noe my LTFT at idle is at 9% and STFT FLUCUATES BETWEEN 3-6% POSTIVE,
WHILE ACCELERATING LTFT drops to 0-2%
STFT FLUCUATES from -3 to -8 %. It has to be a vaccum leak somewhere or exhaust leak , or clogged dirty fuel injectors. Ima swapped out my injectors with denso oem remanufactred .
@@desertheatkicksgee What does the battery voltage look like?
@@AnthonyJ350 12.3V when car is off and when car turns on dropped too 11.5v but immediately started charging up to 13.6v ,
@@desertheatkicksgee It doesn't go to 14.5 ever? What if you Rev to 2,000 rpm?
Can it be cleaned with maf censor cleaner
Also check the EGR if this video doesn't work.
Yes
Given that it's called IDLE air control valve, just as your title states, I'm trying to understand what acceleration would have to do with it? Accelerating involves opening up butterfly so there is no need for IAC during.. in simplest operation.
On my old rig it's closed during all WARM operation, using coolant temp is how it opens and closes. So on cold start, it's fully open and within a few minutes closes completely. On your's, perhaps the computer uses it to fine tune air intake even at acceleration..must be, right?
There wouldn't be a need for it but if that valve isn't operating properly it may be affecting how the induction system works.
@@AnthonyJ350 Very interesting! I'm glad to see you fixed your issue, cheers
@@TheWeirdSide1 Also check your EGR valve if you have driveability issues
@@AnthonyJ350 I finally put my old OEM duatributor back on and intermittent hard start has not occured since. That first idiot mechanic who blew my heads also told me to replace distributor because electrical inside was bad. 14 months later, I finally had a second OEM distributor I could tear apart...there are no electronics inside! My issue was aftermarket distributors from oriellys the whole time.
So now back to original symptom...the cruise control has erratic behavior. It surges and randomly revs high. It also will shut off at times and cruise light just blinks steady every 2-3 seconds. There is no information regarding such a flash sequence. 5 flashes is issue with component, but mine has no information that I can find. Egr system appears to function properly
@@AnthonyJ350 Note: my speedometer cable is jumpy...Apparently there is speed sensor in the dash so that might be my issue with Cruise Control. All this time I thought speedo cable was not tied to any sensors...just mechanical! This is gonna be a fun job to replace cable
2009 Camry 2.4 has rough vibration idle, does the "idle control air valve" be the cause of my problem?
When was the last time the spark plugs or oil was changed?
@@AnthonyJ350 I have a 2009 Camry also with rough idle. I changed the plugs last summer & have had the oil changed abt 1500 miles ago. Any suggestions? I did NOT replace the coil packs when I did the plugs, could that be it? And I have no check engine light on or any lights for that fact
@@jessicaduncan1526 Try cleaning the MAF sensor with a sensor cleaner? Also try a fuel injection cleaner from Lucas. Are you using a top tier fuel brand like Shell?
@anthonyj350 Having a really bad stalling problem with my 2009 camery, do you believe it’s due to a bad iac valve that needs to be replace (changed spark plugs,ignition coils, got an oil change, Cleo the inside of the throttle body) Also check engine light comes on and flashes and the car seems to not go above a certain speed. Plz help‼️
@@Matthewalldayyy You might also want to check the egr valve for proper operation.
