Well, this _could_ be the problem, but my '95 900S has the same problem
with a brand new idle control valve. The idle is a little bit low in
general, but when I turn on the A/C it drops to the point that the car
is no longer comfortable to drive. I've checked fairly extensively for
vacuum leaks, but I haven't been able to find any.

Another symptom I'm currently experiencing is that the car doesn't idle up
very quickly when you put it into drive (it's an automatic).

Yikes!
