Keep messing with that thing, cleaning things up, replacing old sensors, needed PM's, etc. and you may just start turning that severely neglected engine around into something useful. - It is good to see you have made a lot of progress on it.

One thing you might want to do at some point is pull off the DOC and DPF and take some decent pictures of their faces, post em here for evaluation. Maybe send them off to have them baked and flow tested too. Usually only costs a few hundred bucks to have done.

Have you done a couple three oil changes at short intervals (3,000 - 5,000 miles intervals) to help flush the soot and carbon buildup out of the engine?.
