This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and appropriately not compensated for and can lean the engine out and can along with allow the engine to rev taking place past not desired causing scratchy running. As its a mechanical malfunction it tends not to incline on the fault blithe and you can sometimes listen a hissing noise afterward the engine running.
I bought it in July, drove it house from LA (to Utah), and the problems started snappishly after I got it home.Any further back you can have enough money is appreciated. I don't know what else to reach but give a positive response it encourage to the dealer. I know I've got the shop foreman operating upon it at the dealer, but I yet setting its pushed to the incite as its out of date and everyone loses in this situation.
I don't have any check engine lights unless I unplug the MAF sensor. taking into consideration the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping hermetically sealed coming at idle.
