Well, i am trying to diagnose what the hell is wrong with my car. I have cleaned the maf, iac, new plugs, new tps. there is a hesitation (stumbling) when i am doing an easy acceleration or just maintaining a certain speed. but under a quick accel (WOT) the car does fine.
also i notice that when the car hesitates, my fuel pressure guage tends to bounce around as well. any thoughts??
