Having throttle issues.

[bigtodd]

I have been having issues with my throttle pedal not working on my 2007.5 silverado 4.8 automatic. The problem is when shifting from any gear into drive, the truck will take off fine as soon as it goes to shift into second the throttle stops working until the truck goes back to idle. This happens if the truck is cold or warm, I have replaced the pedal and throttle body and no difference. I ran a scan and nothing shows up so maybe it is the tune? I will post the tune file for help thank you in advanced.

Post a log with it happening also

Log everything you can find related to throttle and pedal. There are some related to the pedal, some for the throttle body. Log them all.

found the problem, the throttle follower torque was all over the place. Not sure why I never touched it, put it back to stock and is working great.
