this problem has just been getting started, I will be be accelerating and around 50-65 mph the truck will jerk and it will feel like I hit a speed bump. just a sudden jerk and sometimes more than one happening in a row. not sure if it deals with my turbo exhaust or my fuel pump or lifter. sometimes happends, sometimes does not happen. I need help I have no idea what it could be and I don't know if I should be even driving it if this is happening. starts up fine and idles fine. shifting is normal. help a brother out! thanks!

 

i have a 01 with the same issues
starts runs fine but get on the highway and it jerks and pops puffs of smoke ect.
replaced the fuel filters and the fass ddrp02 seems fine(turn the key and it runs for 25 seconds)
got the p 1693 pecu 0216 codes
connected a pressure test gauge to the shrader and got 20psi at idle and 16psi at WOT
but i didnt have a long enough hose to test pressure driving.
this is a stock truck with nothing but a van aaken D500 bus controller

 

MINE was the van aaken /bully dog can bus controller d-500
