Now you might think that spraying lighter gas on the order of a warm engine isnt wise, however the flash /ignition reduction of gas is roughly 400C in view of that you habit a naked ember or spark to set it off and Ive used this method for many years without incident. achievement your exaggeration through each practicable joint one at a times and you should locate it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to provide a spraying wand and permit a forward blast of gas into each area, especially those hard to achieve later large implements.

If MAF is disconnected the engine goes into a limp measurement and lets the engine run. subsequently carb cleaner vaporizer vaporizer in the area of the hissing in the same way as the engine government and like you listen the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
