Hey guys, Im tired of seeing my check engine light on, and now that I have my car back and running, Id like to take care of the cylinder #1 misfire...I had it scanned at AutoZone and they said it was a bad coil pack. When I search on a few different part sites, I am getting conflicting part numbers...gmpartsdirect says #12578224 is the old part number and that #12638824 has taken its place. I believe that #12638824 is the correct part for my 2007 GXP (like gmpartsdirect says)...I was just looking for someone to concur before I purchase one
