What Causes the Buick Excelle to Shake?
2 Answers
The reasons for the Buick Excelle shaking are: 1. Engine misfire; 2. Worn or loose engine mounts; 3. Carbon buildup issues; 4. Fuel system malfunction. The Buick Excelle's body dimensions are: length 4609mm, width 1798mm, height 1486mm, with a wheelbase of 2640mm and a fuel tank capacity of 44 liters. The Buick Excelle is equipped with a 1.3T turbocharged engine, delivering a maximum horsepower of 163 hp, a maximum power of 120 kW, and a maximum power speed of 5500 rpm. It is paired with a 6-speed automatic transmission. The front suspension type is MacPherson independent suspension, and the rear suspension type is multi-link independent suspension.
When driving my Buick Excelle, I've experienced shaking. Experience tells me this is usually caused by excessive carbon buildup in the engine. After long-term use, the intake valves and fuel injectors get clogged, leading to uneven air-fuel mixture and jerky idling. Or it could be worn-out spark plugs with abnormal ignition causing severe engine shudder during acceleration. Tire imbalance is another common issue - you'll feel the car wobbling at high speeds like riding a boat. If suspension components like shock absorbers leak, the shaking becomes more noticeable when going over speed bumps or turning corners. To prevent trouble, I regularly clean the throttle body, replace spark plugs, and check tire balance. When noticing vibrations, I immediately visit the repair shop for inspection - better fix small issues early than wait for major failures that cost more.
