Really NEED HELP on code 29. I drive 02 Int. 4700 with T444E (which I was told is a Ford Powerstroke) that intermittently gives code 29, mostly while driving but also sometimes at idle. Fuel Command Low due to possible broken/shorted wire or voltage out of range. My mechanic has tried swapping out the gas pedal assembly but that had no effect. He's too busy for troubleshooting but I'm stuck with him so I need to help out on this. When the check engine light is on the truck has a rough and choppy idle that is driving me crazy but that's about the only driveability issue it has. ANY advice on where to look for problems would be greatly appreciated.
