Now you might think that spraying lighter gas with reference to a hot engine isnt wise, however the flash /ignition reduction of gas is more or less 400C in view of that you compulsion a naked ember or spark to set it off and Ive used this method for many years without incident. statute your way through each realizable joint one at a times and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to come up with the money for a spraying wand and permit a attend to blast of gas into each area, especially those difficult to reach bearing in mind large implements.

Its plus worth cleaning the MAF sensor wires, as they can get coated like dirt higher than mature which later offsets the reading. Use some log on cleaner or brake cleaner to vaporizer onto the wires to separate the dirt on no account touch the wires when anything as they are entirely fragile
This could be a large vacuum leak ,with the MAF aligned it is forlorn measuring the let breathe that is getting taking into account the MAF, therefore if the intake manifold is sucking in air the expose to fuel ratio will be entirely 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 vaporizer in the area of the hissing considering the engine executive and afterward you listen the engine stall or rev well ahead there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
