Hey guys, after searching the forum for a thread that could help me, I had to make a new thread. I recently installed fresh ported GT40P heads with spring kit, B-303 Cam and Gt40 intake. The car is a 1992 5.0 Lx 5 speed. I got the car fired up after doing a base idle reset, it idles perfect. My problem is that whenever a load is applied to the car while driving, there is a heavy misfire. I mean, if your familiar with doing a cylinder balance test and when the PCM turns off an injector, it sounds like that. Best way I can describe it. It has a farily new distributor (TFI included) and most sensors. plug wires a motorcraft wires with Autolite 764's.
Not asking anyone to solve my problems I just really need some direction. I advanced base timing from 10 degrees to 15 degrees and definitely saw some improvement but far from perfect. Still heavily misfires.
I will be installing a wideband this weekend to see what my AFR is. any help is appreciated. Thanks guys!
