Cps problem? Need help!
Okay so on my way to work yesterday morning coasting down to a stop the check engine light came on and then the truck started to run like ****. I had the cps go bad about a month ago and I replaced it, fixed the problem. I thought it went out already because it's doing the same thing but I got a new one today and swapped them out and it didn't changed anything. My dad has a 7.3 just like mine so I swapped his sensor out and no change. But when I put the one I just bought out of my truck and into his, his ran fine. My truck is running very rough, shaking the whole truck. It doesn't want to move very much, it sounds like it's firing on half the cylinders or something. Sounds like it's loping. Sometimes it will stay running, sometimes it will just die, but starts back up. The pigtail appears to be okay visually. Any help is greatly appreciated I need to get my truck back up and running.

This is correct. When I have had this problem, it was the outer connecter. Unplugging one connector at a time with the engine running, and listening to the engine will tell you what bank is affected. If one bank is shut down, unplugging one connector from the good bank will probably make the engine stall, while unplugging one from the bad side will not make the engine run any different.
