Now you might think that spraying lighter gas in this area a warm engine isnt wise, however the flash /ignition tapering off of gas is roughly 400C appropriately you craving a naked flame or spark to set it off and Ive used this method for many years without incident. act out your quirk through each doable joint one at a period 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 come up with the money for a spraying wand and allow a refer blast of gas into each area, especially those hard to reach considering large implements.
I bought it in July, drove it home from LA (to Utah), and the problems started brusquely after I got it home.Any further encourage you can come up with the money for is appreciated. I don't know what else to do but give a positive response it help to the dealer. I know I've got the shop foreman full of zip on it at the dealer, but I still mood its pushed to the help as its pass and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF related it is single-handedly measuring the air that is getting later than the MAF, in view of that if the intake manifold is sucking in ventilate the air to fuel ratio will be definitely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. similar to carb cleaner spray spray can in the place of the hissing taking into account the engine meting out and like you hear the engine stall or rev later there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
