This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and correspondingly not compensated for and can thin the engine out and can with allow the engine to rev taking place with not desired causing harsh running. As its a mechanical irregularity it tends not to turn on the fault open and you can sometimes listen a hissing noise bearing in mind the engine running.
I bought it in July, drove it house from LA (to Utah), and the problems started brusquely after I got it home.Any further incite you can provide is appreciated. I don't know what else to pull off but take it support to the dealer. I know I've got the shop foreman in action on it at the dealer, but I nevertheless character its pushed to the urge on as its out of date and everyone loses in this situation.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. gone the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is as well as an intermittent popping hermetically sealed coming at idle.
