I've been driving the Jiangling Yusheng S350 for several years. Once, the car noticeably shook when starting or at low speeds, which scared me into thinking there was a major engine problem. Later, a mechanic checked it and found that the main issue was delayed ignition due to aging spark plugs, a very common problem. It could also be caused by a clogged air filter affecting air intake efficiency, and using low-quality fuel can lead to more carbon deposits, making the engine run unevenly. Sometimes, uneven tire pressure or excessive wear, especially on bumpy roads, can make the shaking more obvious. It's recommended to change the oil and clean the fuel system every 5,000 kilometers, drive smoothly without sudden acceleration or deceleration, and pay attention to the timing of the shaking for timely troubleshooting.
