went for a drive in my car yesterday (1998 cavalier z24), and was running really rough at low idle, and was overfueling ( could smell fuel), thought i overoiled my air filter that i recently put on, so i put my old filter on, ran some lucas fuel injector cleaner and some gasline antifreeze, and filled the tank with fresh fuel, still ran rough and was overfuelling, then on the way home, it started over-revving (almost like it was leaning out) ... any ideas??

Oh, sorry I just assumed that since you posted this in the tuning section that your car was tuned and you were having an issue with your tune. Running on the stock computer I could guess that your issue is a vac leak.
