Hissing Sound

There's a hissing sound when I first roll out in the morning. When the clutch is pushed in mainly but also while idling...not while in gear though....sounds like air rushing out of something....goes away after a couple miles.....any ideas??

I had the same issue several months ago, I found mine to be the Vacuum line from the rear of the manifold that feeds the HVAC controls on the dash. A simple wire tie fixed it so it would not pop off.
