Sounds like that is the line that goes to the AIR pump in the driver side fender well. Don't know if that would cause an idle issue but I don't think so.
I have seen people use starting fluid to track down vacuum leaks. They would spray around a suspect vacuum line and if the idle RPM went up then the line or connection was bad. This is because the starting fluid was being sucked in through the vacuum lines and being burned in the combustion chamber as unmetered fuel.
Have you gone down the check list I provided from the FSM?
Without seeing or hearing the car in person, I believe you have a vacuum leak caused by a bad hose/connection or an open vacuum port or you have a bad FPR.

To test the FPR in reading that if there is fuel in that vacuum line then it's bad, correct?
I didn't go through that list cuz I don't have everything to test those. But I think it's one of these issues.
Could be PCM still. I haven't gotten a scanner to work yet on this. 95's are a pain with its OBD 1.5. But curious of IAC count.
I will also add that when I got this first running. I did not have speedometer hooked up yet. And driving around the idle dropped much more frequently taking out of gear. I bought a converter to read the vss and interpret it to the dash. At first I thought it fixed this cuz it wasn't dropping. But then it started doing it again, but doesn't do it near as much as it did.
