If you have access to an EVAP system (smoke) tester, I would say that would be the easiest way to find out.. you can always go the easy way, and get a can of carb cleaner, use the long tube that sticks in the spray nozzle, and just spray around all of your intake manifold gaskets, TB gasket, and vacuum lines etc, and when the car stumbles idle, or die's completely, you've found your vac leak..
