Yup it sucks the LP in and revs up the engin when you find it. But be careful doing this as not to build up fumes and then hit a spark. tug[addsig]

aceteline is an oxidizer and when sucked into your intake will increase your rpm's slightly indicating a vacuum leak.

not a job for plasma[addsig]

Get a small and cheap LP bottle like what plumbers use to sweat fittings, the run it around vacuum lines and the intake manifold with the gas on and flame off. The engine will idle up when you're near a vacuum leak.[addsig]
