High Rev


Hey Guys, my 98 GT has been at a 1500 rpm rev, even AFTER it is warm, and I'm at a dead stop, its still at 1500 rpm..... what could be causing this? Anyone know?

It sounds like you need a new Idle Air Control valve, they get a carbon build up and hang open or closed at times. Do you have a CEL ?
