Why is my car stalling at idle speed?
Consequently, stalling problems of any kind, are always a challenge to diagnose. The problems that arise from an engine vacuum leak, can be more than annoying. Idle speed, that is way too fast is one of the difficulties, and stalling is another. Confirmation of an engine vacuum leak can be, a very loud hissing sound coming from the engine area.

What is cause of intermittent engine stall?
Common causes of intermittent stalling may include a bad idle speed control (ISC) system, low fuel pressure, loss of ignition, vacuum or EGR leaks, or other problems we’ll get to later in this article. The engine’s idle speed is controlled by how much air is allowed to bypass the throttle via the idle bypass circuit in the throttle body.
Does low oil cause engine to stall?
It is doubtful that the low oil level is related to the stalling problem you describe. There can be many possible causes for an engine to stall as you describe; some possibilities include a faulty crank position sensor, faulty ignition system component, failing fuel pump, airflow sensor, IAC valve, EGR valve, poor electrical connection somewhere, as well as many other things.
