Code 122. tps????
Its running real bad. Wont idle right . Keeps surging up and down, then it dies. The only code i get from it is 122 tps. Would the tps make it run that way ??? I've changed the idle air sensor, and the egr position sensor. Also checked the fuel regulator. What else could it be . Some times it runs smooth. and then it will start loading up, . smoke a little black, then die. Any ideas??????????????
