The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

    intermittently stalling and engine RPMs revving up

    Stalling while driving, not restarting or will restart but then dies within minutes. Surges forward and RPM needle jumps all over the place. Have spent more than car is worth and replaced every sensor
    Known to mankind yet problem still persists.

    Random stalling was resolved by replacing the Mass Air Flow Sensor.

    Car was fine and then it wouldn't stay running one morning. Disconnected MAF to let car run speed density mode and it ran. replace MAF and no further problems.

    Stalling when you least expect it!! Replaced MAF etc - Crank Shaft Position Sensor is next.

    Stalls Intermittently, as if the key were taken out of the Ignition. No Consistent Condition leading to stall.

    Reluctant to start but turns over great, stalls intermittently, idles higher RPM than normal and surges when accelerating. Pulled the MAF sensor connection and everything evened out. Planning to replace very soon......

    Engine just stalls and replaced sensor and now it revs up on its own.
