2009 Mini Cooper S Misfire
I have a 2009 Cooper S with about 114k. I bought it used and have had it for 6 months or so. This past week it started running rough with misfires. I had my buddy who is a car guy and builds his own run the codes. It showed Random Misfires, as well a specific codes for Misfires on cylinders 1, 2, 3, and 4. Because of this it would not seem to be the coil packs, or the plugs. He checked all the other numbers under the details, and they appeared to be acceptable considering the rough running. There is no oil in the coolant (head gasket) and pulling the gas cap while running, there is suction. His worst case at the moment is that maybe the timing belt chipped a tooth causing them to all be out of sync. He is going to continue his research though. I just thought I would ask as well. Any suggestions? Any thoughts as to where to go from there?
