My supra idling dodgy :( Short dodgy video to go with it

I would check for any vacuum leaks and clean the idle control valve.

 

The temp sensor could well cause the issue - Can you go into more details as to when it does it?

 

Start car - Does it do it straight away?

 

Then, does it do it whilst the car is warming up but not when it is warmed up?

 

The advise given about the ECU adjusting is true but that doesn't mean it is right that the car is hunting.

at the time i had this car, all the above suggestions are checked and a few things replaced like, new oem o2 sensor, new spark plugs, IAC cleaned and had no leaks.

then after a video a few members suggested that it was normal, so i never looked into it again for the nearly past 5 years.
