Check the hose clips for tightness and inspect the trunking for any cracks or splits and along with all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best quirk to find a leak is to have the engine government and warm and after that spray can lighter gas /propane or brake cleaner as regards each joint in turn. If the engine rev s going on you ve found your leak.
I bought it in July, drove it house from LA (to Utah), and the problems started rudely after I got it home.Any further assist you can come up with the money for is appreciated. I don't know what else to accomplish but resign yourself to it back to the dealer. I know I've got the shop foreman operational upon it at the dealer, but I still vibes its pushed to the back up as its outdated and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF linked it is only measuring the ventilate that is getting gone the MAF, thus if the intake manifold is sucking in let breathe the let breathe to fuel ratio will be enormously out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. subsequently carb cleaner spray spray can in the place of the hissing similar to the engine direction and past you hear the engine stall or rev later there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
