Thanks, you've ruled this out as my problem. (Car starts cuts out after a few seconds even pressing down on the accelerator. Changed fuel filter, pump, no difference.)
Follow-up: I soaked my IAC in carb cleaner, blew it out with compressed air, repeated, wiped the inside really well, re-installed and now my car starts up perfectly and runs like a top again!
@BellaRocko did it still run good after awhile ? I cleaned mine and it worked good for a bit but it stopped lol, I need to clean it thoroughly now I guess
@@Jruiz1611 Yes, it's still working. Interestingly, I actually ordered an aftermarket one for preventative maintenance, bur with this new one my car would start then immediately shut off. So I sent it back and put the old one back in and it's still running great right now. How strange is that.
@BellaRocko wow lol that's crazy, maybe a bad one ? Idk hopefully wasn't a wrong one either but atlwast the oem works. Btw for anyone else reading I'm going to change mine because I'm guessing mines just out now , but thank you for replying back I'm sure it'll probably help someone else wondering too
@@Jruiz1611 Some car manufacturers/models are very picky with some of their components especially electrical stuff. I've seen this happen several times where I'd replace with a cheap brand from local auto parts stores and would still get the same check engine light code, but then I'd get the part from the dealership and voila the car is happy again.
Thank you for sharing, i believe this can be the problem to my car. Sometimes when i drive my car it turns off while being stopped. When I turn it back on it turns on without a problem. It does not happen everyday but it does happen often.
So I’m having an issue when the air conditioning is running, at a stop, traffic, stop light etc, it will surge up and down from 750-450. Ver noticeable. Could this be the issue? Haven’t stalled yet. It’s also odd it only does it when ac is on. Also tried cleaning it but no change.
my problem was somewhat similar. try to see if the car stalls when it’s warm by turning it off and immediately trying to turn it back on. BUT, since you said it is only with the AC on i’d look more for electrical problems such as battery/alternator etc.
@@nicholaskinard3746 appears it was the IAC. I swapped in one from my old car with double the mileage and all the issues seem to be gone. Debating on buying a new one or running the used part till it stops working
I have a 2000 toyota Avalon with a 3.0. At cold start it idles fine but after warming up it idles rough when you stop. Runs fine going down the road, I did discover 4 ignition coils with cracks on tubes and replaced them but with no results. Also change catalytic converter, cleaned MAF and throttle body but still runs the same.
Ive got a 2010 mustang gt...its got a fairly new throttle body like 2yrs. But a couple of months ago it started idling up and Down. Could it be the IAC??🤔
Made a video.. Could you look at it and let me know your thoughts... I've replaced the gas pump, camshaft position sensor, and throttle position sensor... Still having problems..
I have an intermittent stalling issue. It’s not often it happens. But recently I have heard a buzzing noise on the top of the motor. It’s loud enough to attract attention from pedestrians. While it’s buzzing, there’s no idle issue. The buzzing isn’t constant. It buzzes for a couple seconds, goes quiet a couple seconds, then buzzes for another couple of seconds. Is this the type of behavior you’re talking about. Can idle air valve be that loud?
Wow, thank you so much for sharing this I really appreciate it. I believe I’ve been having a faulty idle air control valve for a few months now what you explained is exactly what I’m going through stalls that stops and especially when I start cold, it has trouble idling , sometimes when the car gets warm, it’s not as bad. Unfortunately this Idle control valve has been discontinued for so many years I can’t get it anymore. Only cheap bootleg made in China garbage that ultimately fails. Anyhow, thanks anyway
Can you "bypass" the IAC by tightening the throttle stop screw to allow air through the TB while at idle? (By keeping the throttle slightly open at idle).
My 2009 jeep grand cherokee 3.7 v6 cranks but doesnt start i take the key out try again and have to push the gas for it to start and it works fine. Can someone please help its been stressing me for days. I was thinking its the idle air control valve but im no mechanic. I recently replaced spark plugs and ignition coils. I also noticed when i have the ac off my rpm meter moves up and down around 600 rpms. Once my car starts it runs and does not stall at lights and the idle doesnt even feel that bad just a little shaky.
I have a 2011 GMC Sierra 1500 got a new engine in January and a new transmission in May after replacing transmission rpms drop falcate after truck is warmed up 30 min or so of driving. I seems to do it between 40-55mph.i can feel the truck hesitating when rpms are furcating betweeen1000 and 1500. I can give it gas and it will come out of it or i can let off then give it gas. But even if i let it get below 40 mph it will act up each time until i get to about 55mph. No Codes no heating up, I have taken it to the GM dealership they say transmission and motor are running like the should. Any idea
Could this also be a Throttle Position Sensor. but to rule out the TPS would use scan tool to see the voltage on it or % . if that voltage on seems ok and not any sudden spikes or drops on voltage as the gas is pressed, if TPS seems ok then its the IAC or dirty THrottle body. NO Codes on scanner, like P0505 for instance
it sure could. mine did this for a while but only caused faulty starts when the engine was warm but not when cold. unfortunately if it gets that bad then the problem is usually mechanical, i had to have mine replaced
Why dont u mention the opposite??? It can also stick open and make your rpm go to 3000 non driveable condition easily remedied by unplugging it and driving to the parts store
Hi I have issue with my 95 hardbody, idle low, step on the gas it drops like its not getting fuel ratio it needed, start up fine that's issues Am experiencing. What could be the issue ?
I have a 2000 ford expedition just bought it it shuts off when I come to a stop but turn back on right away I need help !! Please also exhaust smells like gas

Thank you so much,this video was very helpful.
Thanks so much! My car cranks no start now, and the IAC buzzes for a while even after taking the key out. I will try cleaning it all out this weekend.

mine fights me when i turn it back after a few minutes of running
will a bad IAC cause a hard start in the cold?
Thank you very much bro

I've read that new ones aren't always better (they don't last). It's one of those parts you ought to buy OEM or used in working condition.
Mine only acts up untin it gets warm then it idles fine .
Same here then I took it out to clean it really good when I put it back it made it worst
symtoms?
Same here, could you find the problem?

Up and down could be the pcv valve as well.
Did you ever fix this? I have a 2010 v6.
great video. would it be the iac if the car stalls when put into drive?
Same issue here 2000 gmc yukon slt super low idle as soon as I put it in gear not anough power to move

What's your problem?
What must I do with a new idle control valve

Great video
So if it's causes the idle speed to be higher than normal, what is the cause and fix then ?

Can you let me know where your shop is located
Can you "bypass" the IAC by tightening the throttle stop screw to allow air through the TB while at idle? (By keeping the throttle slightly open at idle).
Yes, it's adjustable
Holy crap, that's me!
Hi boss mine is high rpm during idle.
Question? My car shake when it’s park n I put on my ac. Like it wants to turn off. Is this the problem ?

what if the cars rpm spikes very noticeable when you barely turn the steering wheel?
That's normal. Engine speed increases when turning the steering wheel to prevent stalling due to increased load.
@@Top5AutoRepairs could I send you a video via email? is 500 to 800 rpm normal?
Where is a idle air control sensor/ Valve??? On a 2012 infiniti qx56???
What if idle goes up to 1300. If u cut off car if goes back to good idle around 800
my idle was too high so i put a new air control in now it idles too low and feels like its gonna stall can these things be adjusted?
That's where I'm at lol. Look for vacuum leaks
Check the plug itself too
