A truck came in running of four cylinders. during inspection it was running. When i touched the wire loom it cleared up. Pulling codes also gave me a clue to look into #2. Please remember to look at freeze frame and pay close attention to the definition of the codes. Don't just say "it has four circuit codes" and move on. Suspect them if one is out. Ask why and look at the odd ball closer.
