This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and so not compensated for and can thin the engine out and can along with permit the engine to rev occurring once not desired causing severe running. As its a mechanical malformation it tends not to direction on the idiosyncrasy open and you can sometimes listen a hissing noise considering the engine running.
I bought it in July, drove it house from LA (to Utah), and the problems started tersely after I got it home.Any extra encourage you can provide is appreciated.
