This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and consequently not compensated for and can lean the engine out and can also allow the engine to rev occurring bearing in mind not desired causing rude running. As its a mechanical irregularity it tends not to slant on the deformity lighthearted and you can sometimes hear a hissing noise in the same way as the engine running.

This could be a large vacuum leak ,with the MAF joined it is without help measuring the freshen that is getting next the MAF, consequently if the intake manifold is sucking in expose the ventilate to fuel ratio will be definitely out and cause the engine to stal
