After a very bad oil change experience @ sears for my last oil change, I finally decided to change my own oil. It took me quite awhile to get the drain plug out. It was for the most part totally unscrewed but it refused to come out. I finally resorted to pulling it out, which caused the wire going into the end of the drain plug to seperate (the wire to begin w/ was in pretty bad shape). Now my Check Oil light doesn't go off. Is there anything I can do? I'm thinking a new drain plug w/ the wire attached and connect the new wire.
