1991 Cummins shuts off after WOT
So I ran into an issue and I can’t seem to find it.About two weeks ago my truck started super rough and sputtered with anymore than 10% throttle.Figured it was fuel filter,changed it and still popping.Well I took my truck to a local shop and while he was troubleshooting it he told me my ECU was smoking so I had to get it towed to another shop and $900 later I got that problem fixed.Well now I have my truck back but no popping but it starts pretty rough and will lope/surge for about 5-10 min then idles fine.Now If rev it up steady in P and let off it will cough itself down and then sputter back to life.Now if I burp it(push throttle half way and let off) the truck will choke out and I will have to start it back up.Now when I’m driving I will mash it and it sounds healthy and pulls all the way and then I let off and it will choke out and sputter and then it’ll be good but some times it’ll just shut off.????

Well just some more info,I just went to leave to the store and truck has been siting for 4-5 hours.Started somewhat sputtered and coughed but evened out quick.Let it warm up and went to leave and it was popping couldn’t get over 10-15 MPH so just turned around.Rev it in the drive way and it was as popping and the whole truck got to shaking and was blowing whit smoke.
