engine hunting revving

  1. Intermittent Engine 'Hunting' - O2 sensor/Vacuum Leak?

    Questions, Issues or Problems with the New Beetle
    Hi, My 1.6 (petrol) Bug seems to enjoy revving itself when the clutch is down. The RPM will drop to about 500, and then the car will rev itself up to 1400-1500 (I assume to stop it from stalling?) If I let it carry on, it usually goes away after about 30 seconds, and will start idling normally...
