Can't figure out why it stutters between 35 and 55 mph. It accelerates great and runs down the hyw at 70 mph smoothly. I've replaced just about all the sensors on the engine, replaced the fuel pump and cleaned the fuel system. Any ideas?
Any Codes? Usually if your coil pack goes it's usually on the #4 or even the #3 plug towers. On you tube, ''chris fix'' shows how to check a coil pack, without getting zapped yourself, it does work!
A broken plug. Bet that wasn't easy to find! I had a plug which had the porcelain cracked, it was in a 69 Ford Galaxy with a 302. Had to deal with the periodic misfire til it built up a carbon trace!
