dbw problems tps %is 20 at idle. My friend has a 07 tahoe. And he said one day he was booking it. And after that the transmission dosnt want want to shift it was idle problems. And I hooked up my hptuner and scanned it. And at idle is 20 percent tps. And if I push it all the way and Its says 89 percent. So I'm thinking its the pedal. That can be it no?

All numbers go to a matrix to be looked up as what to do with that voltage. If the map says that 20% is a no load idle then there is no problem. You have to find all the values returned to see what his problem is.
