I recently purchased this truck and the engine was replaced with an engine that has 67K miles. The engine runs great until 15-20 miles down the road. When it gets nice and warm the engine sporatically loses power and turns on the Check Engine light. If I slow down the truck shuts off completely. It will refire but will shut back off until cooled down. I have changed the ignition coil, Wires, plugs, cap. I am completely lost on what other than the ECM it could be! The trouble code that is registering is 42. Any help would be appreciated!
have the same problem?
