If this is a real Saab mech, he will have a tech-II diagnostic computer, which will let him read the fault codes. It's a handheld thingy that plugs in under the passenger seat. Now if your problems are really consistent, he will have had a clear reading from this device. TCS problems can be very elusive, and somtimes will give allsorts of codes on different occasions, but if you're really stuck, it will let you know.
Now even it it would point to a bad throttle body, why don't they just tell you? Have they ever told you what came out of the diagnosis?
I have to tell you that, since you own a '92, you might be in for a new throttle body anyway. Don't know the miles on the car, but this thing is a wear item, and it's just about its time.
I very seldomly hear about a failing control computer ('ETS').
If you want to DIY, you need access to spare parts, because the only way you can do this is by swapping out parts (bleeder/ safety valves). This will save you money because if it doesn't solve the problem, you swap back. But at the point where you really need to go to a new throttle body, you need to have access to a techII because you need to calibrate the system first in order to avoid damage to the new part. Yes, it's a $700 part, but mounting it is peanuts apart from the calibration.

My 2 cents..
