Morning Idle Problems

[imfauxreal]

1992 SC300

When I start in the morning, when engine is still cold the idle goes up and down, but when its already in heat, it disappears

I notice that I dont have the Idle up when you start the car when its cold

If there is a sensor on this, where is it located??

Thanks for the one who will reply

:)

Hi, check my reply to Applejacks idle problem, sounds like yours is the same, it's the Idle Air Control Valve located on the front of your engine, it controls the amount of vacuum your engine needs to run smoothly....

its on the radiator towards the bottom where the drain valve is. the resistance should read 1.48-1.58 ohms at 80 degrees C
