1 Answers
The common causes of idling vibration in the Buick Excelle are usually a dirty throttle body or excessive carbon buildup in the fuel injectors. Additionally, it is advisable to check the condition of the spark plugs, high-voltage wires, and ignition coils, as poor performance in the ignition system or faulty spark plug firing can also lead to such symptoms. Below are detailed explanations of the major causes of severe idling vibration in the Buick Excelle: 1. A dirty or damaged throttle body affecting idle vibration. The throttle body can be cleaned first, but if the issue persists, the throttle body assembly may need replacement. 2. Faulty spark plugs causing misfire and idle vibration. It is recommended to inspect the spark plugs and ignition module for any malfunctions. 3. Aging or cracked rubber components inside the engine and transmission mounts. These components are unable to absorb the engine's operational vibrations, resulting in idle vibration issues.
