Thread: Car Shuts Off When Engine Warms Up

idler air control valve.

Basically controls the amount of air coming in the engine at idle.

It sounds like its failing when the throttle body warms up.

I had taken that off to check.It had alot of carbon on it.I sprayed pb blaster to clean it up. I was tried to move it in and out. Got it to move in when I tried to pull out I pulled it apart. Now i need a new one now
