Some good sleuthing! Vacuum leaks can be a challenge to track down.

Thanks, but I'm sure I have more vacuum leaks... if not between the air filter and intake valves, then elsewhere (master cyl, PVHubs, HVAC, etc.)... everything's nearly 27 years old and dry-rotting away... not sure where to get those tiny (1/8"?) vacuum lines...?
