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?

I've sent Bryan Herter all of my information for tuning my pcm. I have replaced the MAF and the temp sensor is functioning properly. Don't know what else to do at this point.

totalblackbumper, has anyone changed your PCM program? check that your MAF is clean, although when dirty they run lean. check that the temp sensor on the front of the water pump is working correctly
