Ford Repair: intermittent miss in 351w, rotor coil, pickup coil
QuestionI have a 94 E150 with a 351w. It has an intermittent miss and I have replaced the plugs, wires, cap, rotor, coil, and control module. What do I do now? It seems to idle fine but misses intermittenly while driving down the road. Occasionally it will die while at a stop light but start right back up. This vehicle has 132,000 miles on it as well.
AnswerFinding intermittent issues can be quite challenging. The first thing I wonder is what brand of spark plugs you used. Hopefully not Bosch, which do not perform well at all in Fords. The pickup in the distributor could be a cause, as well as a dirty injector. Have you found any codes in the PCM? Typically a faulty pickup coil will set a code 14, and could also be related to the stalling.
