So today I was driving around as usual and shut my car off and went into a store. When I got back I opened my car sat down and closed the door. The seat then moved about 4 or 5 times half an inch in each direction I said to myself what the hell is this thing doing. I started her up and the airbag light went on started beeping, it said "service back up sensors", the sunroof wouldn't work and the scariest thing was when my RPM sensor was bouncing all over the place but he engine was not increasing RPM's!!!! What the heck is going on help!!!!!
