What are ways to tell if your upper intake is leaking?

[CottonBurnerz]

I got a feeling that my accufab plenum might be leaking but I doubt it. However, I would like to know how to tell if it's leaking.

When I was under the hood and pull on the throttle cable.. I get this air sucking sound in the plenum. sshhwwooop shheoospp or something like that.. anyone has done that before and get the same sound?

Just get a can of carb cleaner and while its running with all of the intake tubes in place spray the cleaner around the plenum. If the rpm changes when you spray it you have a leak.
