Message	Hello all, looking for some help and I will try to.keep it simple. Used motor and auto tranny swap. Posted a while back about other issues which I have got sorted out now. My last major issue is that i am running on 4 cylinders. 1 and 2 have no change in idle when coil packs unplugged, all others are fine. I have tried: Switching coils and spark plugs from working cylinders. Pulling coil and plug and grounding them on plenum (good spark and shocked myself) Pulled plenum and spun CAS to verify fuel from injectors (all spraying with valve movement) Tried newer PTU Tried used ecu from crashed Z Compression test (all at 120 to 130, but these were with all the plugs still in engine, so wrong I know. But #'s consistent and other 4 working) So at this point I am lost, please help anybody.
