HELP!!! Car won't start properly!!!
 

hey guys, i just got my car back from the body shop, and now the car has problems starting. When i start the car, it seems fine, but then the rpm all of a sudden drops and it stalls about 1/5 of the time. The other times, it falls to ~100rpm and recovers itself. The battery seems fine, and i just got the car back today, so do you guys think it will go away? or should i have this checked out by my mechanic? spark plugs? By the way, the car wasn't driven for about a week and a half.

your input would be greatly appreciated.

I have been reading about Body Control Module functions for a problem I am having and thought WOW there are so many modules that if disconnected can cause operational problems. Did they have to disconnect anything to do your service?
