i am having the throttle go up and down some when my foot is off the gas.info on this would be much appreciated. i have already rebooted the apps,grounded it to the battery and ran the jumper wire to the pcm. It starts when the truck has been running abou 3 hours or so. i went to the coast and had it wanting to unlock the torque conv and the throttle acting up so ireset the apps while down there. I had problems until i was pulling in the driveway and th throttle went up and and down some but nothing else on the way back.I am thinking maybe i have a bad ground someplace or the apps is going out can i get some good tech help on which way to head first.
