Quick PCM question

[Blacky Bulger]

For the Lincoln LS if I have code P0358 Ignition Coil H Primary/Secondary Circuit Malfunction... is my PCM is pretty much fried? I've done a lot of searching seems like like most people never come back to say the solution only a few threads state that once they've replaced pcm all was well.

I'm replacing the valve cover gaskets and all coils + plugs.... just looking for insight... It does misfire but I thought P0308 was the normal misfire code.

P035x means that the primary circuit has a problem. It could be the coil, the wiring (power to the coil, and/or the wire between the coil and the PCM), or the PCM. Be sure to check the connectors too when you are checking the wiring.

F I thought P0308 was the normal misfire code.

with the LS, the normal code for a coil caused misfire is no code at all... :shifty:

Thanks will do this this weekend.

It was like that then this code popped up... just hoping its not the pcm... but I'll start with the basics.. I may just be paranoid

Easy to do if you read this site enough. A very small minority of LS owners post their problems here; I'd say less than 1%.
