Re: 1998 Grand Am Idles High!

more than likely, your problem is the idle air control motor ( commonly called an IAC ). These adjust air flow at idle and part throttle, and when stuck open, will cause the high idle you describe. It's a simple fix, 2 screws mount it to the throttle body, just make sure you have a scan tool reset your computer when your done, or the new part won't be recognized. (auto-zone and some Advance stores will clear your codes for free)
