Why does my car vibrate when idle?
Motor mounts: It’s the job of the motor and transmission mounts to dampen vibration. When they break, you’ll feel excessive vibration, especially at idle. If they become befouled by dirt or debris, they will deliver uneven amounts of fuel with each engine cycle, causing a high-frequency shutter or shake.
