    I recently got a DTC for P0120 Throttle Position Sensor A Circut and P1130 Air Fuel Performance Fault (Bank 1 Sensor 1) I replaced the throttle sensor and the throttle code went away but the Air Fuel Sensor code came back and then the engine light turned off then back on again for Air Fuel Sensor and then back off. However, in the last two days and especially on a cold morning the truck will buck hard in 1st and 2nd gear and continue to buck in higher gears but less violently and there is a code back for the Throttle Position Sensor and Air Fuel Sensor (Bank 1 Sensor 1) but no check engine light.

    Anyone have any idea?


    ***UPDATE*** It turns out I got a bad sensor from my parts guy. Got a new new sensor in and it runs perfectly.
