How found us = friend
GM tech = jk
question = My 1997 Chevy Monte carlo has a high idle what can i do about it.







JK:

A high idle can be caused by several things.
1. A vacuum leak.
2. Sticking or faulty Idle Air Control Valve (IAC).
3. Carbon build-up in the throttle body bore and plate.
Always have the system scanned for codes first.
