hey guys i was messing around with some wiring on the stang today and i ended up getting a p0358 code which is:

Ignition Coil Primary circuit malfunction.

couldn't find much info on how to fix it?

This is all I could find about that code from my ford service cd




Each ignition primary circuit is continuously monitored. The test fails when the PCM does not receive a valid IDM pulse signal from the ignition module (integrated in the PCM).

[*]Open or short in the Ignition START/RUN circuit.[*]Open coil driver circuit.[*]Coil driver circuit shorted to ground.[*]Damaged coil.[*]Damaged PCM.[*]Coil driver circuit shorted to VPWR[/ul]
Doesnt have a fix sorry
