Have a PO303 reading on my scanner which is cylinder 3 misfire. Changed the plug, and put some electrode grease in the cable. Problem when away for about an hour. Now the Check engine light is on again, and it stutters when i accelerate. Once again aPO303 reading. Also get a small backfire at times, with a loss of power. (recent work i've done ) Changed the fuel filter, oil, oil filter, plugs, cables, EGR valve, DPFE sensor, and the evr solenoid.
