I also notice it will down shift as I slow down.

I cleaned the MAF, TB, New mobile 1 ATF ( great stuff), Oil Change, Pulled the EFI fuse, Total reset of the ECU and still nothing. No codes have popped up yet.

Guessing TPS?

Yep, replacing TPS did the trick for me

Thanks, I tried replacing my TPS with a new one, Does the same thing... Do I need to put the truck into "learning mode" again for it to register a new TPS? What else could cause this issue.

Thanks for all the help!
