What Causes Engine Shaking When Accelerating?
1 Answers
Reasons for engine shaking when accelerating: 1. Spark plug failure: Spark plugs have electrodes, and the gap between them will increase with prolonged use, affecting the ignition intensity of the spark plug. Over time, carbon deposits will also accumulate on the electrodes, which can further impact the spark plug's ignition energy. 2. Engine misfire: An engine misfire can also cause shaking. It is necessary to check whether the ignition coil of the affected cylinder is damaged. After removing the spark plug, a special sticker should be used to cover the spark plug hole to prevent foreign objects from falling into the cylinder. When installing the spark plug, a professional torque wrench should be used to tighten the spark plug to the specified torque. If the spark plug is not tightened sufficiently, it can lead to cylinder leakage. If it is overtightened, the spark plug may break.
