If it is a vaccuum leak you can check by taking a propane torch ( do no light it) with the gas on, and move it around the vaccuum lines. The engine should be on when you do this, listen for the idle of the engine to rise, and you'll find your leak, the propane will act as a fuel and will be pulled into the engine. This is a great way to find any vaccuum leaks.
