Question type: Maintenance & Repair

I had the high idle motor repalced and still no fix. They now tell me the transmission is the problem, i don't agree with this. Tell me if i'm wrong.

trans..maybe, when you start it cold, and let it idle, (even high) will it eventually come down, even 200 rpm?

Once its warm it should be around 600-750 rpm. Does it sound like its idling high or is that what the gauge says? What is a high idle motor, are you referring to the idle air control? Have you checked the throttle position?

That sounds like throttle body problem. A lot of carbon build up maybe, if so clean throttle body and replace the Idle Air Control (IAC) Valve
