My 1991 Grand Prix SE will not idol when it is warmed up. It almost feels like it hesitates a little when you step on the gas after its warmed up. When its cold it runs fine but idol may be a little low. I just replaced the fuel regulator and the plantum gaskets. Also it has been sitting for a while and I just put a full tank of good gas in the tank. I also put some seafoam in the tank to help clean things out. Would you have any ideas on what to look for?
Thank you,
Chad

If you have an idle issue, I would start by checking for vacuum leaks and I would recommend checking the idle air control valve.
