I was thinking the same thing but I didn't read up on this swap enough to know if a PCM change is required for this swap.

yes changed ecm and harness, I dont know ran fine before swap. Got the whole kit from mps auto, its like the computers not working. It will start if i disconnect the fuel pump the die when out of fuel, then plug it back in and will start the idle low and die? Also i pluged in the auto computer i took out snd it will start and run, but idles rough and doesn't seem to run smooth when i give it gas. Also I can start it in gear or with the clutch disengaged, could it be a bad sensor causing this? Th ecomputer they gave me is a T4MO is this right all tranny parts are out of a 94-95 gt
