Thank you Peter , you explain very well and save time for so many . kind regards to you

[@ohmy7554]

Reason for the higher rev range at first start up is older vehicles like these start with a higher idle speed to reach proper operating temperature first. After which it’ll begin to drop and finally idle around the 700 range. If you look at newer engines and how newer vehicles idle at start up, they begin at a low idle because it has better monitoring and sensors to be able to obtain the best air to fuel ratio. These older model vehicles don’t have as good sensors and monitors to keep the rev range low at initial start up.

[@user-hf6kr9wo7k]

But the idiling come down but go up again

[@shipped_my_pants_3000]

[@jeffevansmusic]

Thanks for this video. Appreciated. The Australian 2008 engine is not the same as this. I found my sensor. It's smaller and easier to remove in slightly later engines. After a good clean idling seems to be perfect now. They want $250 for a new one here in OZ so maybe try removing and cleaning first.

Thanks for the info!

Clean the throttle body too.I would remove,clean or replace the PCV also as doing all 3 of there (incl the MAF in this video) Doing this every 4 or 5 yrs whilst doing a service on the car when you change the spark plugs is a good thing,as you won''t forget to do it all in one go.This is what i do...never had an issue on my 2002 Yaris in 12 yrs of ownership.Don't use cheap supermarket petrol is another strong advice,95% of the time i use Bp,Shell or Esso.

[@nrxadrianproplayz4575]

I have a G corolla 2001 auto transmission car, when I start the car first time after a period (usually more than 10-12 hours) the car starts and immediately rpm drops and stop the engine. This happens even in the evening and night. After couple of times starting and pressing accelerator (providing gas) for couple of minutes it works fine. Once it is started it has no problems of starting and stopping it again and again. When I press the brakes while driving and the car is near to stop it starts shaking a lot till it is accelerated to a speed of 20 KM/hour. The problem is more if AC is on. Can you help me in this regards?

[@PeterFinnTheCarDoctor]

Hi, your engine looks like old and weak. So, turn off A/C and if issues are still, replace the engine.

Hello, thanks for your video. One question, I have a 2008 Toyota Corolla with 230,000 km of manual gearbox, 1.8-liter engine, type 1ZZ-FE. The fault is that when you turn it on it starts with 1300 rpm and as it warms up it goes up to 2000, that is, it does the opposite since I understand it should go down to about 900 rpm. and when I'm hot I go out and when I make the gear changes I see that the rpm oscillates between 2000 and 1000 rpm and when I continue the march the minimum is 2000 rpm. If I leave it running stopped the car stays at 2000 rpm. I clarify that with a scanner it does not give an error. Well, we took out the carburetor, total cleaning including the MAF sensor of the filter, I clarify that you cannot take out the IAC valve to clean but the carburetor body was immersed in non-abrasive remover liquids and a lot of dirt came out. We measured TPS and IAC with a multimeter, simulated with power and everything was fine. We checked the pipes that had never been touched and were spotless. We put everything together and it starts doing the same fault. Then I disconnected the EGR vacuum valve and there the rpm's dropped a little but after five seconds it accelerates and when connected it returns to 2000 rpm. The same if I disconnect the PCV valve and it idles at 200 rpm until it shuts off. Could it be a fault in the EGR vacuum valve or Crankshaft Sensor and cams (CKP and CMP)?

Hello Mr. Peter. I have 2005 year Avensis with 1.8 VVT-i engine and I have had many problems caused by abs sensor. Now I have fixed that and now when I stop the car the idle drops to 600 rpm and goes back to normal after few seconds. It keeps doing that again and again every time I stop the car. I have checked the mass airflow sensor, although it's kinda new. Do you have any ideas what would be causing the problem? Thanks.

When the engine is cold like in the morning, it is normal for the rpm to be high for some minutes. It should go down as it reach operating temperature.

Yes

Yes because it revs higher as the cold engine is trying to warm up quickly, so as to reach normal operational temperature as quickly as possible. More important in winter times where the temperature gets really cold and when it snows as well.

[@PeterFinnTheCarDoctor]

+Igor Nirca Sounds OK. No any issues.

[@kgt2252]

+Igor Nirca Dirty Idle Control Valve sensor causes this issue over 90% at a time. Have the ICV sensor cleaned. Also, it is wise to clean the air flow sensor for better fuel economy and quicker acceleration. I have had the same issue with my 2007 Camry. Take care of it ASAP, because in a long run, it will damage your car's alternator and shorten the life of your car's battery. At 500 RPM the alternator may not produce enough electricity to run everything in your car.

[@nircaigor]

+kourosh tari Thanks for info

[@kgt2252]

Dirty mass airflow sensor reduces fuel economy not the idle. It usually the dirty "Idler control valve sensor" that causes the idle to drop to 500-600 RPM. This problem causes the alternator not to be able to produce enough charge and Overtime, this reduces the life of your battery and alternator. This happened to my 2007 Camry, and the only way is to clean the ICV sensor and lubricate the valve, which sits on intake air manifold right after air filter assembly.

[@markchidester6239]

Dude, the area of the MAF sensor you were referring to is the intake air temp sensor. Time is combined with the MAF. The actual MAF part is inside the passages next to the air temp thermocouple. If you look inside these passages you will see two small "wires". That is the MAF part of the sensor. That must also be cleaned. Very carefully.

[@PeterFinnTheCarDoctor]

Thank You for comment. :-)

Hi Peter and all People, In First of all I'd like to say good job with your channel, keep it going! And ask you about my 1.6vvti 124HP Auris 2007. Got RPMs hesitating at 0km/h, its like between 450rpm to 850rpm. And RPMs are hesitating while I'm driving too. Nearly noticeable but about +/- 50rpm. Fast deaf cranky noises when the gas pedal touches floor (in this time I got 2500rpms+, and 3-5gear). - I changed spark plugs already. One of the old one has white cover. Rest of them between black and brown, - Cleaned MAF, Ah almost forgot. ECU doesnt illuminate "check engine". Computer said "no error codes". Im thinking about "knock sensor" and timing chain. Will you help me? Regards Maciej

Peter, i want to ask a question about engine vibration. I have a 2009 Camry with 2AZFE ENGINE, 2.4L. 215,000 miles. When i am stopped at a light, and the engine is in gear, i get a noticeable vibration. If i shift to neutral, it goes away or is much better. I have the following new parts i installed trying to fix the vibration. New Toyota OEM motor mounts, all 4. New spark plugs New alternator, Denso New water pump. New serpentine belt New coil packs, all 4, Denso. New coil pack connectors, Denso, all 4. New valve cover gasket New intake manifold gasket Newer AC compressor. Has 71,000 miles on it. AC works good. I think the engine is being loaded down when in the drive gear. Engine rpm us 750-850 when idling. Gave you seen this? Engine runs good when driving. Thanks! Dave

[@PeterFinnTheCarDoctor]

Hi, maybe your engine need rebuild. New piston rings ?

[@ratpatootie8623]

Had rough idle issues on my 2010 Corolla for years. Did the basic checks; air filter, mass airflow sensor cleaning,etc. Turns out it was a leak from the intake manifold and a sticking PCV valve. Replace the valve since you already have access to it when replacing the manifold gasket.

[@PeterFinnTheCarDoctor]

Thanks 👍

[@nonoisleem]

hi Peter Finn Thank you for your video.. I want to know did you mean that this air leak causes a bad idle speed in cold temperature & then become a normal idle speed in normal operating temperature? OR it causes a normal idle speed in cold temperature & a bad idle speed in normal temperature? I want to tell you my problem in my Corolla 2011 1.8L the problem once I turn on the car in the morning it runs smoothly with 1600 RPM idle speed, then it decreases to 620 in normal temperature which causes vibrating in engine, this vibrating increases when i stop at a traffic light & the RPM decreases slowly to 600 then 550 then 500, i should move the gear pad to N instead of D to decrease the vibrating little, same thing happening in R, when I try to park my car & put it to R with some breaks it vibrates also and i feel it when i set on chair, I should press fuel pedal to remove the vibrating, the crazy & not understandable thing that when I turn on AC, the RPM increases too much to reach near 1000 RPM & the vibrating goes away, there is no any vibrating in the engine, what the hell is that?? I searched & spent a lot about it, I CHANGED: (spark plugs - fuel pump - throttle body - air mass flow sensor - coils) all parts are new from Toyota dealer.. I cleaned injectors by a mechanic handy.. I need a professional mechanics to advise me for any solution or possibilities of this,, Thank You & best regards..

[@ScaleCrawling]

On my 2005 Corolla the idle when cold is steady, but when the engine is warm the idle goes up and down between 600 rpm and 1000 rpm. This makes it tricky to handle at stop lights as it will stall if you don't give it gas, and when you do give it gas it's hatd not to give it a bit too much gas, making it seem like you're a noob or an old lady.
