2002-vw-passatWhen I start my car, it will rev by itself and if I press the throttle it will cut out unless I wait about 20 seconds, it doesn’t matter if I’m in gear or not, it will still cut out and then when I come to a stop after driving, it will start revving by itself again. I don’t know whats wrong.

This is a classic description of a vacuum leak. Usually a hose has a crack in it or an intake gasket.

What do I need to find a vacuum leak
