i have a 89 civic si...with the a D16y8 motor in it. The car has a hasport engine harness and a ecu harness from LOCASH. I took the car for tuning and we saw that the car was making no power. We check all the basic things and then we went to the injectors(RC440's). After checking them we came to the conclusion that 2 and 3 arent working, so we swapped 2 3 with 1 4 and still same problem...so then we went to injector wiring. We ran 4 direct wires from the ecu to the injectors and still same problem. Basically the problem is if i pull out inj 1 4 the car almost dies out and bogs but if i pull out 2 3 thier is no change in motor idle. We used my tuners ECU and my ECU and its the same thing. Can someone please tell me why im having this problem
