My 5.4 liter will enter a forced idle mode while I am driving. This has happened three times in the past forty six miles (one hundred and twenty five minutes of running time). There is no common time that this happens ie: cold and wet or dry and warm. I pull over turn the truck off and then it starts rough but does start each time. The truck does run fine other than this. The vehicle displays three error codes, P2104 TAC - forced Idle Mode, P2111 TAC - stuck closed, P2111 TAC - stuck open. Ford does not recommend cleaning the throttle body. With that amount of miles on the vehicle I do not think I should have to replace the whole throttle body. I was thinking maybe the throttle body sensor? If you feel it is one of these two items how hard are they to replace?
have the same problem?
