Im a member of FTE OBN and PSN have been for years revently got invited here by 94f450sd he told me i could get more help here,
Ok i have a late 94 f350 cab and chassis with a 7.3 powerstroke diesel and it runs ruff to say the least, it misses at idle shakes the truck, when its cold it real bad going down the road it vibrates and has almost no power till the engine gets warm once the engine gets warm it starts running better dont miss as bad and has decent power, if its setting and idling and i put my foot on the floor it will rev clean till around 2300 rpm then it starts missing bad and pouring bluish white smoke out after around 3000 it clears up and stops missing and runs clean till the rev limiter, never throws A CEL
Since i have had it i have changed the passenger side valve cover gasket external plugs and the UVCH because it had burnt wires, also replaced the CPS, and the fuel filter, and disbled the EBPV, then i have run countless buzz test and cylinder contribution test and pulled the codes countless times, heres the weird part, sometimes it passes the BUZZ test BUT i can always here that i have a few injectors that dont sound right??? but sometimes it does pass the test, except i can still here that the cylinders dont sound right, it always passes the cylinder contribution test, but clearly i can rell its not running right
i have also taken the plug off at the IDM and OHM all the wires there, all the wires for the injectors brought back 3.2, all the other ones brought back OL like they were supose to, so then i took my idm off and put it on my buddys truck, his still ran perfect, so im at loss here, please help me get my psd running right so i can actually enjoy this thing
Sorry for the huge post

anyways i been thinkin about this.im kinda wondering if you may have a few loose armature screws.under the solenoids on the injectors there is an armature plate that has 1 screw in the center of it.i have heard of these coming loose.i know its a wierd torx type screw but dont remember the size.
