HIgh Idle


My 1994 Saturn will idle at 1,500 RPM’s. Otherwise, runs fine. Any ideas?


Check for a vacuum leak.


Make sure the throttle plate is closing fully. A sticking (open) iac (idle air control) valve can, also, cause this. Disconnect it and see. No change? Clean it (internally), and its air passages, with Carb/Throttle Body Cleaner.
