89 ford van
I replaced the motor in my van with a motor from a 93 f150 and it runs terrible. They where both 5.0s the only thing that was different between the two of them was the distributer. The engine ran great in the truck, It runs great in the van until you put it in gear, then it misses and barely moves. It is at Ford, they have no clue, too old to scope, so they keep throwing parts at it but its not doing any good. Any suggestions would be greatly appreciated. Thank you
