Vacuum leak in a hose/fitting somewheres, most likely. Carefully look. I've had that myself and found the tube leak. My tube comes off the power booster for the brakes, but my car is not your make. But just look around.

The vacuum-powered motors open and shut internal duct doors to route the air. Could also be a bad vacuum motor.
