This could be a large vacuum leak ,with the MAF similar it is unaided measuring the freshen that is getting as soon as the MAF, thus if the intake manifold is sucking in let breathe the freshen to fuel ratio will be no question 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 can spray in the area of the hissing in imitation of the engine meting out and taking into account you listen the engine stall or rev difficult there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
