FYI, I finally replaced the ICV on my 90 C2, and it does idle better, although still not perfect. It seemed to take a few drives before it "optimized" for whatever reason, but it's much better than before I started working on the problem, when it would invariably stall at idle once the engine warmed up, especially if I turned the AC on.

I had already improved the situation considerably just by cleaning the old ICV with brake cleaner and spraying the insides with a bit of WD40 once the cleaner dissipated. But the new ICV gives me a little more confidence that I won't stall in the middle of an intersection while another driver takes aim...
