i sounds like a smog pump noise but the air flow is being restricted. there are two valves connected to a rubber hose from smog pump, check to see if those are functioning.....

Check hose that comes from the brake booster to the rear of your upper intake. If the idle is sitting high and you dont have brakes, it's most likely that.
