need help on code 29 please
02 Int. 4700 with T444E intermittently gives code 29, Fuel Command Low due to possible broken/shorted wire or voltage out of range, sometimes while driving and sometimes while at idle. Usually this only happens after the truck has been running for at least 4-5 hours. Other than the choppy idle (can't stand it) there are no other drivability issues. My mechanic has tried swapping out the gas pedal electronics but no effect. I don't know much about diesel engines so any ideas will be welcomed.
