I have a 1987 900S with Bosch's LH 2.2 fuel management system. On start up, my car has eractic idle as well - for the first 2-3 minutes or so. The air mass meter is the cause for this. Once the 02 sensor has warmed up it can provide the LH computer with the proper signal to give a proper air/fuel mixture for smooth idle. Although I am not fimilar with 1991 fuel management problems (I believe you have LH 2.4.2), I do believe that you have a problem similar to mine. In other words, some electronic sending unit is not giving the proper signal to the LH 2.4.2 ECU. On page 200-12 (of the Bentley Saab service manual) there is a chart. Symptom C ("eractic idle") should be of some help to you in figuring your problem.
Hope this posts helps.
Happy Saabing.
