I got a pretty bad vacuum leak... bad enough it causes the car not to idle. I could rev if I hold the gas pedal down when I start it and eventually it will die out... but the main thing is I can't pinpoint exactly where its at. It sounds like one of those party favor things that you blow on (sort sounds like a duck call). Any ideas what it might be. I think I have zeroed it down to somewhere in the throttle body but id like to know what would make that sound =S
