This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and correspondingly not compensated for and can lean the engine out and can as a consequence allow the engine to rev up gone not desired causing prickly running. As its a mechanical anomaly it tends not to aim on the anomaly buoyant and you can sometimes hear a hissing noise later than the engine running.

This could be a large vacuum leak ,with the MAF combined it is forlorn measuring the freshen that is getting once the MAF, so if the intake manifold is sucking in freshen the freshen to fuel ratio will be completely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. considering carb cleaner spray spray can in the area of the hissing in the manner of the engine meting out and in the same way as you hear the engine stall or rev far along there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
