Re: TJ 2000 engine RPMs doesn,t return to idle
1. Have you checked the Idle Air Control Motor?
a. Pull it (it's loacated on the Throttle Body.).
b. Use Spray Carb cleaner to clean it and the hole in the TB it mates into.
2. Pull the Battery Negative cable.
3. Let the computer -re-train itself.
4. Use Propane, or water, or carb spray and look for a vacuum leak around the intake manifold and throttle body.
