@@PeterFinnTheCarDoctor My problem with my 2007 Toyota Yaris is that when I start it idles at 2000 RPM and even after it warms up the idle does not go down, what do I do? I thought there was a Idle adjustment on top of the throttle body bu there is not. any suggestions?

@@warriorplutotrent3827 if you have concerns like the engine running rough, or bad idle speed fluctuation and etc: Get some throttle body and carby cleaner, and spray it into the IACV intake port beside the butterfly valve in the throttle.

Also Toyota Auris 1.4vvti with same engine from 2006. no setting mechanical idle throttle. Only over ECU. There is a small nut like you have on old Corolla but they welded that small allen hole so you can not use it. Funny thing is everything else on the engine is the same, almost. Those engines from Toyota are bulletproff with timing chain.

Still have some. If I put my foot on the gas with other on brake it runs smooth when I hit between 800 and 850 rpm. Right now in park my idle is 750. Should I adjust idle to solve this vibration issue in drive when stopped? Thank you Note: new spark plugs, coils, injectors, fuel filter, maf, clean throttle body and iac valve and air filter
I didn't know you could alter the idle speed on E12 Corolla's as i've never seen that nut and grub screw on the throttle body and thought it was computer controlled like it on most modern cars. I know that Toyota were one of the last if not last to keep making nice and simple cars in the 2000's.
Hello peter,First i would like to thank you for your great videos, and i have a question; i have a 1zz block and i want to know to assemble this engine all the details should be from 1zz or i can use other details from other models??
Love your corolla content you're amazing thankyou. I have low idle around 600 instead off 800 or 900, makes me stall a lot or rev too hard taking off, throttle body might be a little sticky to .
Good job 👍🏻 throttle cables stretch just like on motorcycles and dirt bike atvs etc of course you can adjust you idle like this lol that’s an idle screw 😮😂 nice vid .
Hello peter ... Do you think maybe adding a new airflow that is metal is a big plus since adjusting the idle speed gives more air to the engine ?and thanks for you video definitely im going to try it on my corolla
Oh my god because of the code of the check engine light was give me I change the air flow sensor /the gasket of the throttle body / the Idle Air Control Valve / noting works / and I look your video and found out it was that , because the idle was at 2000 rpm Thank you sir
Hi Peter. I made this adjustment which worked nicely at first but then started idling poorly again and gave me a PO505 code which i mever got before. Any idea what the cause could be? Thanks for all yoir videos!
Isn't the idle controlled by the "idle speed control valve" (the valve is just under of the adjustment screw, you can see the electric connector just below on the video) on VVti engine? they do have that adjusment screw too but why would you use it?
It's for the idle fine tuning. Sometimes ecu fails to adjust idle properly, engine stalls in traffic stops, and that's when you need to adjust this. I own this exact same car.
Hi Peter my Corolla has same engine in video Toyota Corolla 2004 model, but mine has problem on idle it goes from 800 to 1200 rpm back and forwards on idle, I havent had look yet was going change spark plugs as been over year since changed, looked at Haynes manual and it said could be other things what is your thoughts , i watched your video which shows good how to higher the idle speed or lower. but mine seems to be going from normal to high without pressing the pedal.
Peter, Wifes Corolla idles perfect after initially going up to almost 2000 revs on cold start up. Just wondering is it normal to rev to this extent when cold. The car idles smoothly when warm.
Technically, its a hex key/wrench. Allen is the most notorious name which has become synonymous with the tool...just like a crescent wrench..kevlar is another example. Kevlar is the name brand of a material made by DuPont
Thanks so much for the video sir. My 1ZZ Toyota engine suddenly raised it's idle speed from 650 rpm factory set up to 2100 rpm. Can I adjust it's idle in the manner you have done or it calls for something else?
@@PeterFinnTheCarDoctor I adjusted idle to until zero but the idle speed just dropped Abit from 2100rpm to 1400 rpm. What could be the problem? I have replaced intake gasket, cleaned mass airflow sensor and throttle body.I checked vacuum hoses and replaced cracked pipes but the problem seems to stay.
@@chandamwila1754 Probably Idle Air Control Valve of throttle body got jammed. You can spray throttle body cleaner in that hole, if that doesn't fix the idle then you'll need a new throttle body. I'm telling this from my personal experience.

No vacuum leak found. 4- MAF sensor is working fine. 5- spark plugs were inspected , not blakish , no oil on them. 6- car mileage is good, good pick up. 7- fuel pump and filter are found OK. 8- Engine mounts are also fine. kindly advise any solution how to fix?
As far as I am aware idle speed cannot be adjusted with that Allen key screw on any engines with a throttle body. That screw is just a stop for the throttle butterfly and not an idle adjustment, which is electronically controlled. If you turn that screw in then the butterfly comes away from the throttle body and the air will no longer go through the idle circuit. What I have learnt in my 35 years of experience is to NEVER adjust your idling via that screw. You turn the screw until it’s just touching and then one quarter turn in. Idling is not adjustable on these engines.
It comes in handy when your car stalls frequently at traffic stops, you can readjust the engine to idle at a higher rpm in such case. I think they put this adjustable screw for a purpose, may be for a temporary fix.
Adjusting it the way he did helps if a new part such as a Idle Control Sensor was added that has a slight bigger opening for air which increases RPM’s.
No need if idle is okay? I think I idle around 700 which I thought was proper. I was told to consider it for acceleration issue but I don't think that makes sense.
ok , took wifes car for good long run and absoutly flogged it ( drove it like it was stolen ) next day idle had changed and kept stalling , i did the above and this fixed the problem , cheers mate
Hi peter tried this today because of a low idle for many years 2005 Corolla but it seem to just rev to 2000rpm then when I lower it down it goes to the bad idle again doesn't want to go to 800rpm its high or low idle even with small adjustments is it something I'm doing wrong.
Hello peter finn. This is safe to do? Mine is 600 rpm when normal temperature. Feels low and car is shaking. I hear that 600 rpm i normal for vvti. Is this true?
Mines as low as 600 sometimes it idles about 750-800. I believe 750 was factory- dont quote me though. Im gonna bump it up to about 9-1000 on my 02 1.8
on my 2009 there is a adjustment, there is a allen head set screw with some clear glue covering it, its right on the top. If you turn it to far, it will pop a check engine light, just reset the code, go in small increments, and I suggest you mark the setting before you turn it, so you can see how far you have turned it, and retest.
Please help if you can. 2ZRFE 1.8 Digital Throttle Body, Ive relearned/reset/ battery disconnect,/ cables crossed without battery 20 minutes, replaced MAF x 2, replaced alternator, replaced camshafts sensors x 2, Crankshaft sensor, air filter, spark plugs x 3 times, coil pack x 2 times, injectors x 3 times, replaced head gasket and seals, replaced the coolant, changed oil @ 3000, changed transmission @ 10,000, replaced coolant fan, and preformed a battery reset and still having an idle whenever at idle and at warmed up plus whenever coolant fan kicks on it drops the rpm. Whenever I put ac on it smooths out. Oh ya I replaced water pump, Serpentine-Belt, timing chain, Crankshaft bearings too. Anyone wanna help.
I couldn't find the name of it so what i did was go to auto zone got a pack of m5 bolts the long ones. Some m5 spacers and used the nut. Youll have to use alot of spacers but it works
River Browning ... the man speaks truth! It's alllllll electronic. Disconnect the battery, clean the air flow control thingy, connect the battery and turn key to on...wait like 5 mins, then start. There'll be a shit ton of smoke coming out of the exhaust, that's the cleaner fumes, but then the computer will adjust itself to the proper idle. My idle dropped a few months later...I replaced the filter and cleaned airways, repeated the cleaning bullshit, and its runs fine. If the idle drops when the air con is on, clean out the gunk in the pulleys and fan. Make sure everything moves freely. If it's still idling like shit... change and gap your plugs correctly.
dude your messing with the tps setting which will throw off your timeing controlled by the ecm leave it alone your having a idle air control vale proublem or a vacuum leak.
The throttle position sensor is attached to the throttle plate for this engine. The throttle plate is the idle air control valve after the engine reaches operating temperature. The open loop is controlled by an actuator below the throttle body. The actuator is controlled by a coolant temp sensor. The actuator opens the high idle valve when the coolant is cold. Closes it when warm then the air flows through a tiny gap in the throttle body. That gap is made by that set screw. When the plate turns so does the potentiometer type position sensor.
This fixed my corollas idle problem. Thank you! ;)

Hello peter finn. This is safe to do? Mine is 600 rpm when normal temperature. Feels low and car is shaking. I hear that 600 rpm i normal for vvti. Is this true?
+MysterY MysterY This is safe to do and 600 is Ok rev.
Mines as low as 600 sometimes it idles about 750-800. I believe 750 was factory- dont quote me though. Im gonna bump it up to about 9-1000 on my 02 1.8
Can I do this on a Toyota Corolla 2010? My mechanic says it’s not possible because my throttle body is electronic
Right
on my 2009 there is a adjustment, there is a allen head set screw with some clear glue covering it, its right on the top.
If you turn it to far, it will pop a check engine light, just reset the code, go in small increments, and I suggest you mark the setting before you turn it, so you can see how far you have turned it, and retest.
Hie sir my corolla does delay when pressing gas pedal and picks after a while

Please help if you can. 2ZRFE 1.8 Digital Throttle Body, Ive relearned/reset/ battery disconnect,/ cables crossed without battery 20 minutes, replaced MAF x 2, replaced alternator, replaced camshafts sensors x 2, Crankshaft sensor, air filter, spark plugs x 3 times, coil pack x 2 times, injectors x 3 times, replaced head gasket and seals, replaced the coolant, changed oil @ 3000, changed transmission @ 10,000, replaced coolant fan, and preformed a battery reset and still having an idle whenever at idle and at warmed up plus whenever coolant fan kicks on it drops the rpm. Whenever I put ac on it smooths out. Oh ya I replaced water pump, Serpentine-Belt, timing chain, Crankshaft bearings too. Anyone wanna help.
I have reduced my own but the speed is still increased what should I do
Ok. Noted
Does anyone know the name of that bolt, I snapped it...
Im trying to figure the same thing out. Mine snapped to and i don't want to drive my car like this. Have you figured out what its called?
Peter my engine management lite is on my 2002 corolla 1.4 vvt.i and there is a slight splutter from the engine do u know what this would be please..
Please, do video to me. I listen then.
Spark plugs.
maybe I missed it but what is the RPM supposed to be
800 ish,
800
Where can i buy replacement screw
Used throttele body
What's the name of that bolt?
I couldn't find the name of it so what i did was go to auto zone got a pack of m5 bolts the long ones. Some m5 spacers and used the nut. Youll have to use alot of spacers but it works
This does not work for the 2009-2010 models. They have an electronic throttle body. The car is also fuel injected.
Hi My Friend and Thanks for feedback. :-)
How to adjust electronic throttle body? I have corolla 2010 1.6L manual gear car. Having same problem. Please help or reply me any useful video link.
My cable is loose like a lot how do I make it not loose
Noted 👍😀
Video states 2000-2010. 2007 has "Throttle by wire" and not any adjustment.
👍
anyone know where the idle adjustment is hiding on a 2009 corolla 1.8 L
There is no adjusting
River Browning ... the man speaks truth! It's alllllll electronic. Disconnect the battery, clean the air flow control thingy, connect the battery and turn key to on...wait like 5 mins, then start. There'll be a shit ton of smoke coming out of the exhaust, that's the cleaner fumes, but then the computer will adjust itself to the proper idle. My idle dropped a few months later...I replaced the filter and cleaned airways, repeated the cleaning bullshit, and its runs fine. If the idle drops when the air con is on, clean out the gunk in the pulleys and fan. Make sure everything moves freely. If it's still idling like shit... change and gap your plugs correctly.
Peter Finn Hi. If this is the case, then how do I adjust the high idle problem? I tried to change the throttle body but it's hardly compatible with it
Much fix, very rev. Vroom
Many Thanks 😊👍
dude your messing with the tps setting which will throw off your timeing controlled by the ecm leave it alone your having a idle air control vale proublem or a vacuum leak.
Ok
😂
The throttle position sensor is attached to the throttle plate for this engine. The throttle plate is the idle air control valve after the engine reaches operating temperature. The open loop is controlled by an actuator below the throttle body. The actuator is controlled by a coolant temp sensor. The actuator opens the high idle valve when the coolant is cold. Closes it when warm then the air flows through a tiny gap in the throttle body. That gap is made by that set screw. When the plate turns so does the potentiometer type position sensor.
07 has flyby wire.
Ok
Why dont you ever reply back !!!!! In so many feeds ive messaged u
