1st check MVD, EPA (or what ever governing body in charge) rules and see if a M90 is exempt from emissions testing being 31 yrs. of age and it complied with all Federal safety and emission laws at time of production. I would doubt my M88 would pass either.
Probably not ECU, as car usually won't run at all, but could be in extreme situations. Should be able to get away with full tune-up (including timing) & new O2 sensor.
Check your AMM, TPS & AIC using recommended methods and values described in the Bentley Manual which is available under the manuals link on site entry page.
If you don't already make sure you run premium fuel.
A bad cat converter usually presents as a rotten egg smell from exhaust but would change out O2 sensor before going down that road, if it is the cat, tell them you want it back and take it to salvage yard which usually gives a really good price (about $100 in New Mexico) as they are filled with platinum beads.
If you drive mostly in the city may consider Sea-foam treatment, taking it on the highway, run the snot out of it "AKA the drive it like you stole it method" to clean out the pipes.
IHMO. Since Saab went out of production and Saab garages are about nonexistent, unless mechanic is extremely familiar with the unique systems in these cars, I wouldn't trust their opinion as have seen to many Saabs butchered and misdiagnosed by "normal" shop mechanics. For example there is one sitting at a local garage that the mechanic says it is bad fuel pump and says you can't find them anymore. Obviously hasn't heard of eBay, eEuroparts, Rock Auto and others.
If possible do the work yourself, learn the car and save a boat load of mechanic fees, the only major tools needed are a digital voltmeter, timing light and maybe a sparkplug wrench (if you don't have the Saab tool kit). In my area shop fees run about $125/hr. based on "book" time not "actual" time spent working on it. Good luck.
