First post! Howdy y'all. I have heard good things about these forums.
Anyway, my truck (see sig) has some weird issues. It runs great, then all of a sudden it will lose throttle, pedal it a little and it will come back. It is also shifting very erratically. 1st sometimes hangs, 2nd to 3rd normally fine, 3rd to OD and lockup it hunts really bad for both.. Going to check alternator for Ac voltage tomorrow and add/clean grounds and some of the normal things. Anything else I should check or do? Has a brand new Industrial Injection VP and Fass lift pump. When the truck runs, she runs good. Fast, strong, shifts GREAT.
Also, no codes thrown! Validated with Snap-On scanner..
All suggestions appreciated, thanks!
