Re: Help! Grand Cherokee Orvis 1999 4.0 Problem?
There seems to be a cable loom which passes at the back side of the engine and which could be touching the engine and have a shaved through wire, causing a short once in a while.
I also heard of the PCM housing screws which could be too long and after time cause a short inside the PCM. Shorter screws did solve this problem.
