Checking a TC is free - so go for it.
With a reman engine (trust me is was nothing like new) it (chain) should be new.
Key is new or fixed junk engine. Doubt much is new but the paint! Sad but true. Remans generally last about 50k and blow up. That totally depends on who did it but it tisn't new. If you really could find true new crated engine for an 89 you are doing better than I can,

That's usually the area it's at on those.
There isn't any loose connecters or single wires just hanging there in that area is there?

Unplug the vacuum line to the EGR valve and drive it.

You haven't really solved your problem. You have only isolated it. Now you have to find out what's causing it so you can resolve it and get the EGR working again.
Could be the EGR valve, Could be the EGR solenoid

Glad to hear you found the problem.
But that was just step to find the problem. Either the valve has the wrong orifice washer or weak spring but shouldn't be left disconnected.
Probably the easiest fix would be to put a vacuum delay valve inline in the vacuum line. This way you'll have a working EGR system...
