OK, I was racing my car pretty hard at a 1/4 mile track we marked off. After we were done we flipped our hoods up and I noticed my tranny was smoking slightly, this made me a little concerned. The next day I went to start my car and I noticed that my RPM’s Started off at 2, and was stuck there, as I drove my car that day they went down but not compleetly to 0 when Im not moving. As my car sits and I start it back up they are back up to 2 when I am not moving, not giving it any gas or nothing. Can someone please help me and tell me what is wrong, because something is wrong!! plz help!
