What Causes the Jerking of CVT at Low Speeds?

[DeJoshua]

CVT jerking at low speeds is caused by engine carbon buildup or spark plug failure. Here are the relevant explanations: 1. Engine carbon buildup: When carbon builds up in the vehicle's engine, it not only leads to reduced power and increased fuel consumption but also causes unstable idling, resulting in jerking during cold starts. Additionally, if the spark plugs' ignition efficiency declines, the combustion conditions in each cylinder will vary significantly, leading to engine vibration accompanied by noticeable jerking. 2. Spark plugs: This issue may also be caused by insufficient engine warm-up. When the engine is cold, the oil's fluidity is poor, preventing effective lubrication of the engine pistons, which results in severe jerking during operation. Once the engine temperature returns to normal, this phenomenon will disappear. If the engine continues to jerk when warm, it is necessary to promptly visit a repair shop for inspection and maintenance.
