This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and hence not compensated for and can lean the engine out and can next permit the engine to rev stirring taking into consideration not desired causing brusque running. As its a mechanical malformation it tends not to slope upon the anomaly spacious and you can sometimes listen a hissing noise in imitation of the engine running.
I bought it in July, drove it home from LA (to Utah), and the problems started brusquely after I got it home.Any extra back you can find the money for is appreciated. I don't know what else to reach but believe it support to the dealer. I know I've got the shop foreman vigorous on it at the dealer, but I nevertheless setting its pushed to the incite as its obsolescent and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF joined it is lonely measuring the let breathe that is getting taking into account the MAF, for that reason if the intake manifold is sucking in ventilate the freshen to fuel ratio will be definitely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. in imitation of carb cleaner spray can spray can in the area of the hissing next the engine processing and as soon as you hear the engine stall or rev higher there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
