hey, im new one and not very good at english but i will hope that somebody will help me.
Ok, the car is Honda civic eg4 1992-1995. Engine is D15Z1 with D16Y8 intake manifold, P07 ECU. Last week i fully repaired the engine, all was replaced new, except distributor and spark plug wires. i also did wire tuck so all wires was cut and resoldered good. No CEL codes. The problem is that the 1 and 4 cylinder is misfire, i checked the spark, that was good. i also checked injectors, they ware good. but when i checked the injector wiring there was some problem, the yellow/black wire is getting battery voltage, the other wire is pulsing but when i unplug spark plug on 1 and 4 cylinder i have no changes, and the exhaust pipes coming from 1 and 4 cylinder is barely warm. so i take plugs to injectors from the 2 and 3 cylinder injector and connected to 1 and 4, the are working. so i assume the problem is with injector wiring. maybe ecu, main reley? distributor?
