So recently I took off my upper intake to get to oil driveshaft to replace the gasket it on it. Anyways in taking it off I broke one of the electrical connectors to fuel injector #6 and fixed it yet all the other fuel injectors seem to get power and get ground from the fuses and the ECU. However, the car runs like a turd nugget and just rattles and has a terrible pickup. The #2 fuel injector seems to not have ground but when having a jumper on the wire the engine ran better but not great. IF anyone has any thoughts I'd love to hear them.
