Advise given above is good.
When my harness went bad, random fault codes, including misfire codes, was all I had. Eventually the problem gets worse, including hesitation, popping (backfiring through the intake manifold), missing at idle, etc.

Enrique at MB Motors tells me that random codes are always the first symptom of a failing engine wiring harness.
