1997 7.3 running rough
Need help, I have a 97 f350 7.3 301,000. It started running rough no matter what gear it is in. I changed the ipr, icp, cps, and the fuelfilter. Still throws the check engine light and hardly runs with no power.

Most likely the UVCH connections. That are the two plug in connections on each valve cover. Unplug them and look for melted pins, especially on the outer edges. Need more info on the truck if they have ever been replaced. They supply power to the injectors and glow plugs.
