Garage Cabinets, Garage Storage, and Garage Organization

ok so i crashed y car, and now theres this odd idle like the engine dies sometimes i don't think it has to do with the crash because i didn't hit the engine at all, so i'm thinking its the cold i've only had this thing for about 8months now so never drove it in this cold of weather before but now and the guy that owned it before me never drove it in the winter so idk, i'm think 16 degrees is a bit to cold for my CL55, anyone have any other ideas?

I was in scotland for 2 years with my CL and never had any problems with driving in cold weather. The car was winterized of course but it has seen 60 below 0 quite a few times. The only problems was the paint would start to chip off and a few hard starts until warm.
Hope this help.
