I'm back again, car still running rich. I've set fuel pressure to 43 psi, changed egr valve, replaced catalytic converter and 02 sensors right bank. Car still is running rich and backfires when it gets warm. The MAP is the only thing I haven't replaced. While driving when the vehicle goes into overdrive it sputters, give it some gas then it goes away until in overdrive again. Can someone please help me out?
