    So, I just failed my emission test. Said my # 5 cylinder is misfiring. I replaced coil and plug with no change. Now I find out that GM has valve seat problems with this engine. If it is a common problem do you think GM will stand behind their engines and repair them or do I have to pay the total amount >|???
