Iam in Hot Springs Ar......with a a badly missing 460....My scanner shows nothing .....Iam looking for recommendations for a shop to scan my engine beside Riser ford....I cannot leave my MH a few days...
Just a thought....do you have catalytic converters on your coach? That's exactly how a car I had acted when the converters began to come apart. They will let enough exhaust thru until they get really hot and expand, stopping the exhaust flow, then it bucks and crys. Like I said, just a thought.
