Rough idle after hard to start hot/cold problem fixed.
I have an 01 f350 7.3 with about 330000 miles on it with a rough idle only on acceleration. The issue began after hard to start cold/hot problem was fixed. It has a vibration to it on acceleration so at first I thought it was a tire or suspension problem but the vibration stops when you let off of the gas. Things I’ve done so far to it is replaced gpr, glow plugs, valve cover gaskets, icp sensor, cps (grey), ebp sensor and tube which was plugged up, new batteries and new positive cables, and had a low turbo boost pressure code removed which did not come back. I’ve been told by the dealership that it has passed the injector buzz test and they can’t find anything wrong with it. It’s now showing on contribution test injector 3 & 8 codes. Any suggestions will help thanks : >

i think it may be a fuel pressure issue? That’s my next step I guess
