I've been chasing a high idle on my '97 Aero for over a year. If you search you'll find some references to this condition in the archives indicating that it affect some of these cars but not enough that there's an easy solution. I've gone through the VC gasket change, PVC loop replacement, AIC cleaning and replacement, vacuum hose replacement and my idle is down to about 1000 rpm. At least it doesn't turn the cel on anymore. My idle was at 1500 rpm at its worst. I found replacing the vacuum hoses was a big influence in correcting this problem but it hasn't cleared up completely. I used 3/16 fuel hose with zip ties at the ends. I'd be really interested in any other solutions that anyone might have.
