32 - EGR Error (EGR was just replaced with the correct part # from my car and it was a genuine GM part)

41 - Ignition Control Open Circuit

42 - Igntion Control Grounded Circuit

46 - Pass Key Failure (WTF?)

51 - PCM/PROM/Flash Error

Car is fairly stock; K & N FIPK, Hurst shifter, skip shift eliminator, Hooker aerochamber muffler, deleted cat. Thanks. My car is running fine, that is why I'm confused about the codes being thrown.

Does anybody know what these mean?

Have you tried clearing them? And if so, do they come right back?

I did have them cleared, the check engine light hasn't come back on yet, I'll have to wait and see if it does. Are these not really that major of a problem then? Codes dealing with ignition and PCM have me somewhat worried.

Sounds like you might have a ground problem, either at the engine or at the PCM.
