Thanks for the tips!
I popped the hood this afternoon and had at look at my turbo bypass valve. I blew into the holes but nearly popped a lung instead, so I guess that checks out. The baby hose coming out of the top and running back to the turbo looks pretty old and crackly. In pulling it off I severed the lip and had to snip it with scissors. Put it back on *very* carefully. This hose doesn't really look like the rest of the Saab hoses. Those are all mostly clean and spongy. This one feels like it's ready to go, or gone already in a spot I didn't notice.
I pulled the DIC and it looks to be in pretty decent shape, comparing it to some pictures I've seen of bad ones. The inserts around cylinders 2 & 3 are melted just a little bit, but no oil leakage like I remember seeing in a picture somehwere. The plugs below look relatively new, although I couldn't find a socket extension long enough to actually pull and inspect them.
I also noticed another seemingly after-market hose. This one very short, coming into (out of?) the upper left hand corner of the top of the head. It comes from (goes to?) the turbo *right* next to where the "suspect" baby hose from the turbo bypass valve inserts. It also meets another metal pipe that runs along side the left side of the head before plugging into the casing around the DIC. Anyhow, when I removed the plastic cover for the turbo, I pulled this hose right off, then realized its just sitting on this little junction that runs into the head. No hose clamps or zip ties or anything. Long story short, I started the engine and pulled the hose off, and it's pulling air into the turbo. I plugged it with my finger for a moment and I'm guessing the ECU kicked it up so she wouldn't stall. I hooked it back up to the junction and heard a pretty loud hissing sound. Unhooked it, plugged it for a moment longer, then let go, and she stalled. What is this one? (Again, please bear with me. I'm no mechanic...)
Hopefully replacing these two will set her up at least for now. Hard to imagine the clown who installed this last one without securing it at all.
Thanks for any and all advice,
Elijah
