Started out as cylinder 3 misfire, normal highway driving, I replaced plugs and coil packs, did not help. Then engine over heated, checked coolant which was low. Shortly after realized coolant has been leaking to nowhere and white smoke started coming out of the tail pipe. After some reseach I find out this a problem Ford knows about, so im hoping they are held responsible.
