Finally ran codes

Well I finally ran the codes. We didn't have too bad of a winter so didn't need the traction control. But now I have check engine light. The codes I got from Advanced are P0172 and C1100 which I think deal with the check engine light. I am more worried about that than the traction control. It seems to be running fine. The only thing I noticed is that when its cold on start it putters a bit. But driving and everything there is now misses or rough running.
