What are the causes of engine vibration in the Buick Excelle?

The causes of engine vibration in the Buick Excelle are: 1. Engine misfire; 2. Aging or loosening of engine mounts; 3. Carbon buildup in the engine; 4. Fuel system malfunction. An engine is a machine that converts other forms of energy into mechanical energy, originating in the UK. It can refer to either the power generation device or the entire machine including the power unit. The Buick Excelle is a premium mid-size car launched by SAIC General Motors, with dimensions of 4419mm in length, 1814mm in width, and 1487mm in height, and a wheelbase of 2685mm. In terms of power, the Excelle is equipped with 1.3T and 1.0T Ecotec dual-injection turbocharged engines, delivering maximum power outputs of 120kW and 92kW, and maximum torque outputs of 230Nm and 170Nm, respectively.
My Buick Excelle has been running for four or five years, and recently the engine has been shaking badly, especially at idle where the entire steering wheel vibrates. I took it to my regular repair shop, and the mechanic said it was caused by aging spark plugs. After replacing them with a new set, the shaking stopped immediately. It could also be due to excessive carbon buildup in the throttle body blocking the air intake or worn engine mounts losing their damping effect. My takeaway is that such shaking in Buick Excelle models is common in older cars. It’s best to inspect the ignition system and filters every 20,000 kilometers and clean carbon deposits promptly to avoid major repair costs. Also, avoid low-quality gasoline and fill up at reputable stations to minimize clogging from impurities. If the shaking gets severe, don’t push it—delaying repairs could damage the engine or increase fuel consumption, costing more money and compromising safety.
