Message Well, I used the boost leak tester and it wouldn't hold pressure long enough to try to listen for leaking air, so I spray carb/choke cleaner around while idling. The brake booster to plenum hose is culprit number one, and I think the upper plenum gasket is culprit number two. I sprayed the carb cleaner down under the plenum at the rear-center and got a reaction in the idle, so unless there is something under there that I'm forgetting, I may be pulling my plenum...again :(
