Thank you for the tips, I have determinced that after swapping injectors 1 and 2 that I have no injector problem, after checking continuity of the harness deduced I have no harness problem, after checking resistance at the ECU pins 3,4 and 5,6 I have 10 ohms resistance, so it seems the ECU is good, the primary sympton that I notice is noticably less drop in engine speed when plug wire #1 is removed, I also checked for spark on that plug, it's firing. Maybe this is someting mechanical but compression on # 1 cylinder is 164 psi hot, that would tend to eliminate camshaft,valves, head gasket, rings, as being problematic, maybe it's a fluke, the good news is I have already resoldered all the joints in the ECU I could get to and it still works, I even squeezed the harness connectors together, to ensure proper contact on the ECU pins. Overall I still
prefer FI to Carbs, when it works it works great, D jet was so way ahead of it's time, it is a well engineered system in my opinion, I will investing further into the contacts in the distibutor , I have a dwell meter somewhere,thanks.
