What Causes Slight Vibration During Car Idling?

[VonGiselle]

The reasons for slight vibration during car idling are as follows: 1. The engine mount, which serves as the engine's shock absorption system, is primarily responsible for absorbing minor vibrations during engine operation. When the engine mount ages, it can cause vibrations during idle. 2. Ignition system failure, such as spark plugs "misfiring," can lead to car idle vibrations. It is advisable to promptly visit a 4S shop or repair facility for maintenance. 3. A dirty throttle body or excessive carbon buildup in the fuel injectors can also cause car idle vibrations. Cleaning the fuel system is necessary, and using higher-quality fuel or adding fuel system cleaner during refueling is recommended.
