Engine missing with new injectors
I just installed My injectors (stage 2 DIY kit from DPP) into my 02 PSD. The truck starts great and revs in place great. driving down the road acceleration seems better but from 35 - 55 mph i get a shutter in the truck. It feels like the torque converter is slipping but thats not it. I checked for codes and there is nothing. I also replaced the vavle cover wiring harness, valve cover gaskets, and glow plugs. If i stomp on the gas it doesnt shutter, if i let off the gas it stops shuttering. it will only shutter when i am just cruising. when i first went for a spin it was really bad. as i have put more miles (20 miles) and run time on the motor (1.5 hours) it is getting better. I have heard from several people that this sometimes happens when injectors are "fresh rebuilts" but i have never come across this, so i dont know if they are BSing me or not. the truck has a cold air intake (just cleaned), a 4" exhaust turbo back. I have a programer on the way with custom tunes but its not installed or here yet. any info would be great.
