93 2.3 with the TC turbo on the stock motor. The check engine light is on and its running really rough. The plugs have tons of carbon on them. I had 19 lb injectors with a 55 mm mass air and fuel pressure is set at 35 lbs 150 fuel pump and boost is at 5lbs. I changed the plugs, put the stock injectors back in with the mass air, new ecu, new DIS black box on the side, new 02 sensor, new DIS grey box on intake manifold. Disconnect exhaust to see if teh cat was clogged(its fine) checked compression its good, checked the timing its good, new fuel filter, pulled the codes said something about high votlage at a sensor?? what should i check next, coil pack?
motor still running rough
