Yeah I have heard horror stories on the plugs. Mine have been changed before so they should be good. It was just the type of plug that was put in from the factory.

Taz- in that picture, i would consider the garage to be dirty. Usually it is actually cleaner than that. We have an oversized 2 stall attached to the house, a 12x18 and a 32x48 that we just built that I park my pickup in.
