Hello All,
The coil pack in a friends car just died and a replacement was ordered.
The only difference noticed on the new one was the #1 & #4 swapped places.
Both had the 4 wire jack with three wires coming to it from the car's harness.
When we hooked it up and bolted in with new plug leads installed, the car idled fine , but when revved it broke up sounding like a terrible misfire , the two inner plugs (2&3) werent firing.
I did a search on this board and tried the solutions mentioned , but those referred to the MPI , & I got no success.
The grounding issue mentioned in a past thread might be the culprit , but I dont know which ground wire they addressed that solved the problem.
I'll upload some pictures of the two coil packs , the one with the wires is the new one ...
Any suggestons to solve this problem?
