My Ford 05 F-150 Lariet went into failsafe mode on the freeway, had to merge to the right and emergency stop in order to shut truck completely off and then restart right away. This is the second time this truck has put me in a dangerous situation. My codes are P2104 and P2111. What do you guys think, should I replace the TPS. Replace the TB unit and then flash the program with a portable unit like an X3? Thanks for the feedback.
