The best habit to locate a leak is to have the engine giving out and warm and later spray lighter gas /propane or brake cleaner as regards each joint in turn. If the engine rev s occurring you ve found your leak.

This could be a large vacuum leak ,with the MAF joined it is without help measuring the air that is getting when the MAF, thus if the intake manifold is sucking in ventilate the ventilate to fuel ratio will be completely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. considering carb cleaner spray spray can in the area of the hissing in imitation of the engine giving out and in the same way as you hear the engine stall or rev forward-looking there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
