My 330 has been idling very low lately sometimes to the point where it feels like the engine wants to shut off. What could be the problem?

    The low idle condition with your 2003 BMW 330Ci may be caused by a dirty throttle body. Debris can build up around the throttle body restricting the air flow at idle causing a low idle condition. Cleaning the throttle body with some brake cleaner sprayed on a shop rag may help restore the idle speed to a more normal range.
