1996 psd help

[swamp_ratt]

Got a 1996 psd here with 126K on the clock. It has a new idm, and it runs like crap. It idles really bad and has blue white smoke. The smoke gets worse as the engine warms up. If you go to free rev it, it has almost no throttle response. It takes 30 seconds or better to reach 1k rpm. It is fresh swapped into a truck that has 207k that had 2 melted pistons. The truck has sat since 06. Has 400+ compression on all. Had it scanned a couple weeks ago and was a bad idm. So the idm was replaced. Was scanned by ford and is a ford reman idm. Driving down the road it takes a block or better to reach 25 mph

Sorry, back two cylinders are 350+ compression

did you put new injectors in it when it was swapped? what kind? used or new?
clean the fuel system when it was swapped? was it cleaned or all replaced?
FPR may need replaced, or could be about out of oil, should probably start with checking that being that's easiest.
fuel filter can cause rough running if it's gunked up.
it is also possible that the remaned IDM is no good.

Sounds like a fuel/oil issue.....
