Idling problems 97 Gt
It idles at 600 rpms. There's a little sputter here and there. When I first start the car it stays at 2000 rpms and comes down slow. Also I think that there is a vacuum leak but I can't find it. I've sprayed the whole engine with carb cleaner. I recently replaced: EGR valve, ICT, AIC, fuel filter, spark plugs. I cleaned my throttle body and air filter, MAF sensor, ACT sensor. I don't know what the problem could be or if idling at 600rpm is normal. All help and comments appreciated!
