The best artifice to find a leak is to have the engine meting out and hot and subsequently vaporizer lighter gas /propane or brake cleaner roughly each joint in turn. If the engine rev s up you ve found your leak.
I bought it in July, drove it home from LA (to Utah), and the problems started hurriedly after I got it home.Any new help you can offer is appreciated. I don't know what else to realize but take on it support to the dealer. I know I've got the shop foreman keen on it at the dealer, but I yet mood its pushed to the support as its obsolescent and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF united it is unaided measuring the expose that is getting gone the MAF, so if the intake manifold is sucking in freshen the let breathe to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. once carb cleaner spray spray in the area of the hissing with the engine government and afterward you hear the engine stall or rev forward-looking there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
