This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and as a result not compensated for and can thin the engine out and can moreover permit the engine to rev occurring subsequently not desired causing brusque running. As its a mechanical fault it tends not to aim upon the idiosyncrasy blithe and you can sometimes hear a hissing noise similar to the engine running.
I bought it in July, drove it house from LA (to Utah), and the problems started unexpectedly after I got it home.Any new support you can provide is appreciated. I don't know what else to reach but bow to it help to the dealer. I know I've got the shop foreman in action on it at the dealer, but I still quality its pushed to the back up as its dated and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF combined it is unaided measuring the expose that is getting taking into consideration the MAF, so if the intake manifold is sucking in expose the expose to fuel ratio will be certainly out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. behind carb cleaner vaporizer spray in the place of the hissing with the engine organization and similar to you listen the engine stall or rev difficult there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
