What Causes Slight Vibration During Car Idling?

[Chloe]

Introduction to the causes of slight vibration during car idling: 1. Engine mount issues: The engine mount acts as the shock absorption system for the engine, primarily responsible for absorbing minor vibrations generated during engine operation. If the engine mount is faulty, these vibrations can be transmitted to the steering wheel and the interior of the vehicle. Therefore, when the engine mount ages, it can cause vibrations during idling. 2. Ignition system failure: A "misfire" in the spark plugs can lead to idling vibrations. It is advisable to visit a 4S shop or repair facility promptly for maintenance. Delaying repairs may result in increased fuel consumption, difficulty starting the engine, and reduced driving power. 3. Dirty throttle body: Excessive carbon buildup in the fuel injectors can also cause idling vibrations. In such cases, cleaning the fuel system is necessary. Using higher-quality fuel or adding fuel system cleaner during regular refueling can help prevent this issue.
