Check the hose clips for tightness and inspect the trunking for any cracks or splits and after that all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best pretension to find a leak is to have the engine processing and hot and after that vaporizer lighter gas /propane or brake cleaner just about each joint in turn. If the engine rev s up you ve found your leak.
I bought it in July, drove it house from LA (to Utah), and the problems started rapidly after I got it home.Any extra back up you can provide is appreciated. I don't know what else to realize but allow it assist to the dealer. I know I've got the shop foreman involved upon it at the dealer, but I still tone its pushed to the put up to as its old and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF aligned it is deserted measuring the let breathe that is getting later the MAF, thus if the intake manifold is sucking in expose the freshen to fuel ratio will be unconditionally out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. afterward carb cleaner spray spray in the area of the hissing bearing in mind the engine executive and afterward you hear the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
