| Code Help! I have a 2006 GMC Duramax, LBZ. My poor truck is trowin codes like crazy, so far the codes that I have come up with are. PO401, POO3A, PO108, PO299, PO234. I clear them out with my Edge chip and they'll come right back once I drive it again. I was going to take the chip off and take into the dealer, what should I expect when they look at it? and can I drive it for another week? |
