I'm not an expert, but here's my two cents worth.
First, it sounds to me like the AC problem and the misfiring are two separate issues that only seem to be connected. I could be wrong, but I don't see any way the AC could make the car misfire as it seems to be doing. If the engine is barely running, I suppose that might have some kind of deleterious effect on the AC, but it's unlikely there's a causal connection between the two.
Second, if the chug-chugging is intermittent (you mentioned that it works for a while, as in leaving the mechanic's shop), then my guess is a failed DI casette. This could also light up the CEL. Swap with another known good one to check (this is a very easy procedure--you can probably do it with the torx screwdriver in the Saab mechanic's kit).
Third, I don't think the O2 sensor would have this much of an effect on the way the car runs. Nice try, though.
Fourth, run, don't walk, from those mechanics. If they didn't even suspect the obvious (DI, etc.) then they should go back to working on lawn tractors.
Good luck. Keep us posted.
