#2 stops firing. Change the plug and it will occur again anywhere from one month to one minute. Swapped coils to see if problem followed coil. It didn't.
Diagnostic shows P0302, #2 cylinder misfire detected; and
P0352, Ignition coil B Primary/Secondary Circuit.
I can fathom the misfire bit, but the P0352 throws me. If there's any kind of problem with the coil why didn't it transfer when I swapped it for another? If there is a problem with the wiring, why does it go away with the changing of the plug?
Hello Mr Fixit...If memory serves me right, the PO352 B fault code would indicate #4 cylinder coil and PO352 A for #3. The
Possible causes ...faulty spark plug...faulty spark plug wire..faulty ignition coil pack..faulty PCM...open or short in wiring from PCM to iginition coil pack. To accurately troubleshoot and determine the problem you will need an oscilliscope and a diagnostic scanner. Without these you are basically guessing as to the cause.
The ignition control module is integrated into the PCM and a faulty ICM can definitely cause this trouble code...and i have seen my share of faulty PCM's.
Hope this helps and the best of luck to ya.
