Ok guys I just put two new injectors in my truck (3,8) and now it is starting to do the same thing. It starts fine and idles fine, but once you take off it acts like it is running on 7 cylinders. I have actually felt it kick to all 8 and the truck runs fine. It runs fine once warmed up completely, it just does this when it is cold. I used a superchip to pull PO237 PO743 PO603. I just put a nvk4 pcm in and it changed nothing. I installed my DI regulated return about 1 month ago and have been stock every since then, so I am rulling out a chip bringing up the PO603. Need some help this is pissing me off.
