after wheeling/mudding for about an hour this afternoon, my tj wouldnt start back up afterwards. took quite a few tries, with the airbox disconnected. there was some mud in it but not much. on the drive home it drove like sh!t, clutch was horrible, really shaky, then slowly fixed itself. was this just from mud getting in the clutch area or something else i should check out? also came home and cleaned out the airbox and got a new filter.
