Hi there I'm new to the forum.
I've got a 2001 psd and I can't figure this out for the life of me.
It starts great even at -20 last week, idles smooth and runs good until you accelerate in o/d as much as you can without downshifting it will start stumbling bad and then come out of it. It won't do it when the motor is cold though??? Had it at the shop and they said it had good fuel pressure and it passed a buzz test on all 8 injectors. But #3 failed CCT.

New fuel filter, oil change, icp and cps.

Also no codes.

Here's a video of what it's doin. I need some guys. This thing is getting annoying and the me hanic wants to tear into the injectors next week.

Also I forgot the truck has a gtp38r turbo, 70 hp injectors, 6637 intake, stock straight piped exhaust, and an 80 hp superchips ( same result with or without chip)
Thanks guys I really need to get this figured out.
