    If your check engine light comes on with codes P2103 (TAC motor circuit high) and P2111 (TAC system stuck open) Your truck will go into limp mode and will not go faster than 10 MPH.

    Solution: Remove and clean the throttle body with carb cleaner. Lube the throttle shaft with WD40. Problem solved. Cheaper than a new $900 throttle body.
