Having an issue with my 96 non PI 4.6 T-Bird. Changed out the spark plugs after it was having some low RPM power issues. I took off the plug wires and cleaned them and put the Dilectric grease on. Put in Bosch Platinums which were already at correct gap. After all was said and done, I had a huge miss. Re-did everything and the miss was still there. Just changed out my plug wires and the miss is still going. Any suggestions? Just thinking what could I have screwed up in that plug change that would cause that miss?
Need a code reader next and going to go from there. Thinking coil pack right now, if not than possibly one of the injectors. Sure hope I'm diagnosing it correctly as a miss. Like I said, any suggestions?
