Ok well when I take it back to gm I'm going to have them do a compression test and a relearn on the tb.Unlike the G8 V6, the GT doesn't have a do-it-yourself at home no special tools required relearn procedure and believe reprogramming requires a Tech II or equivalent.....and then realized something, when I changed my maf I also cleaned my throttle body with the crc throttle body cleaner and I remember something about messing it up if you push the blade in with your hand to clean it. So I took the cai off and checked around for left over residue, disconnected the negative battery cable for 38min. Put cai back on. Started for 3 min. Turned off a min started back for 3 min. Hoping maybe it does the relearn for tb position...
