You can also try a smoke machine, but I don't think a small leak would cause you so many issues.

That works best on major leaks on an intake. The flammable spray fluid test. A vaccuum hose leak can be difficult to find at times. As sometimes the components fail and will create the leak as well. This one of the reasons why Toyota moved to more electric sensors as time when on to get away from vaccum issues.
