Chad,
The AMM (Air Mass Meter) is probably the culprit of the stalling when cold, during warmup.
If you know someone with a SAAB like yours (1988-90 non-Turbo OR 1989-93 Turbo), and their car acts fine, swap their AMM into your car.
Make SURE the ignition key is "off" for at least 30 seconds before removing the AMM electrical plug. Then, swap in the good aMM. Try a cold startup on your car with the donor AMM. If there's no more stalling, you need a new or rebuilt AMM.
Rebuilt ones usually start at $100 or so. Also, you could take a chance on a used AMM on eBay, they go for only $25-50 there, sometimes. Caveat emptor.
As for the wobbly ride in wind, I'm battling that too, and still tracing the root of the problem. My front shocks are only a year old, but rears are probably the age of my car (1984)!
