Re: 2000 Cavalier Idle Surging High and Low
it could also be and intake gasket leak if the gasket shifted and created a leak the idle would bounce around but would idle really high. I have had it happen to me once it took me 3 days to figure out it was the damn gasket i jusy replaced but had shifted. i would start small with the vacuum leaks if the IAC valve went bad it would more than likely barely run
