AH yes. I actually like mine! It's the Idle air control valve on the back of the throttle body. There is an idle adjust screw facing the front of the car. If not adjusted properly, or if you need a high idle due to vacuum loss from a nice extreme cam, it will whistle. Also, if it's a Cali car, it might be the vacuum valve for introducing air to the exhaust system, although I have never seen this myself.
