Ok I couldn't resist going out and checking a couple things. Vacuum line on the MAP sensor looks fine, but two very weird things. The manual throttle plunger/bladder thing right above the battery does absolutely nothing now. Push it in and nothing, engine does not rev. That's a vacuum-controlled item right? The normal mechanical throttle cable works fine.

Even weirder...my vacuum pump, which has never worked at all since I got the car, is now running!!! WTF?
