Other than running rough, it has a hard time getting up to speed on the highway. Sometimes it stumbles a bit.

Have you checked fuel pressure? How old is the fuel filter?
Not recently. Not sure how old the filter is.

That jives with the passenger side SPOUT plug being missing. I always pull them for a smog test as it reduces NOx by a large margin, but the engine bogs down at anything over 3K.
Until you can find a a SPOUT plug, you could make a jumper by taking a short length of stiff baling wire, flatten the ends with a hammer until they fit snugly into the slots of the female part of the connector and bend it into a 'U' shape. When done, see how the car behaves.

The entire thing is missing, it is just two wires barely protruding from the wire loom. I had just enough length to wire-nut them. I have a spare harness with both connectors I think, but I'm little reticent to pull things off that one.

I assume that you have screwed a nut over the two bare wires such that they make contact. You might want to check their continuity to make sure in case they are corroded. After all, you have the code 219.
OK, for my 90 I'm showing pin 36 on the EEC IV harness and pin 5 on the DIS harness. I can fiddle with that on Saturday most likely.
Haven't had the chance to take off the intake yet due to rain, but I measured the resistance from the harness to the DIS and was in spec. However from the harness (pin 39) to pins 16 and 40 my resistance was 6K ohms and it should be over 10K. Working on checking that out now.
SPOUT "jumper" is soldered. That may be a dead end.
