Car's been running very rich and stalling etc, today took a look at sensors, MAF reading with engine running was normal, but with the engine off and ignition on it stays at 2.95g.

Obviously this is supposed to be 0, so I tried to unplug the maf sensor and same thing, 2.95.

Is it safe to say it's bad wiring or a PCM issue? I'm wondering if a bad ground is throwing off the MAF "reference" voltage.

A MAF issue should throw a code. Is the light on?

Not for anything MAF related unfortunately. Took the PCM out to inspect for damage she didn't find anything obvious.
