BMW N20 unstable idle speed and jerking are caused by: 1. Failure of the vehicle's ignition system; 2. Loosening of components in the ignition system; 3. Severe carbon deposits in the engine; 4. Aging of engine components; 5. Excessive carbon deposits in the throttle; 6. Untimely replacement of the air filter; 7. Excessive carbon deposits in the fuel injectors; 8. Problems with the ignition system; 9. Unstable oil pressure. The idle speed of a car is not a specific speed but refers to an operating condition. When the engine runs without load, it is called idling. When the engine is running and the accelerator pedal is fully released, the engine is in an idle state. The engine speed during idling is called idle speed, which can be adjusted by modifying the throttle opening size, among other methods.
