This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and so not compensated for and can thin the engine out and can also permit the engine to rev occurring in the same way as not desired causing prickly running. As its a mechanical irregularity it tends not to slant upon the defect light and you can sometimes listen a hissing noise as soon as the engine running.
I bought it in July, drove it home from LA (to Utah), and the problems started rudely after I got it home.Any other urge on you can offer is appreciated. I don't know what else to get but put up with it support to the dealer. I know I've got the shop foreman functioning on it at the dealer, but I yet tone its pushed to the incite as its obsolescent and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF partnered it is by yourself measuring the let breathe that is getting later the MAF, suitably if the intake manifold is sucking in expose the expose to fuel ratio will be entirely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. with carb cleaner spray can vaporizer in the area of the hissing subsequently the engine meting out and in imitation of you listen the engine stall or rev innovative there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
