Thanks! IAC Valve was the problem

Thanks, David!
You were right: IAC was the problem. I searched the board for that term, and a lot of information showed up.
Particularly great where Michael Briand's illustrated instructions on how to clean this valve (http://pages.infinit.net/mlbriand/saab/iac/page1.html). Michael himself credits the original instructions to Dean.
I followed them, and it solved my problem.
The first day after the cleaning, the behaviour was really erratic: the idle would go up and down randomly all over the scale. (I got really worried that I screwed things up.) But, on the second day, it stabilized itself. Not quite at 1000 RPM (as I've read it should), but on 1200. However, this is good enough for me, as I got my peace back. It keeps steady on this mark.Maybe the oil that I used to lubricate it with needs a few more days to settle and distribute itself properly.
Thanks a lot for the explanation and the guidance.
