About a week ago i had a bad misfire and my service engine light was blinking. When i got home i saw that the spark plug wire was siiting on top of the header. I put all new wires on and the light went away and the car ran better. Well today i was looking at my aeroforce and noticed a misfire in cylinder # 3 although it is not nearly as bad when i burnt the spark plug wire. I put in all new autolite 104's tried a different plug wire and swapped out coil packs and it still was misfiring. Any input would be helpful. could it possibly be the injector? thanks
