Check everything associated with the idle, I am not familiar with the b17's but throttle body, idle set screw, any wiring/vacuum connections in the area. It just sounds like your car is not catching it idle when its spinning back down. You might even try turning the idle speed up a little bit as a first (and free) thing.
