Throttle problem
I’m doing a 2003 5.3 in a 55 and am loosing throttle response. If I rev it up sometimes it will die and the engine light comes on with code 1518 (TAC Module). After it’s restarted there is no pedal response. It idles fine. Also if I clear the code and hold the pedal down suddenly it will rev up then just go back to idle even with the pedal to the floor. If I slowly accelerete it will rev a lot higher. Kinda stumped.
