What are the symptoms of engine misfire?

[Lilliana]

Engine misfire is characterized by noticeably stronger vibrations than usual. Engine misfire refers to a situation where one of the cylinders is not functioning, typically caused by a failure in the ignition system of that particular cylinder. Most household vehicles use inline four-cylinder engines, and if one cylinder stops working, the engine's smoothness deteriorates, resulting in more pronounced vibrations and shaking. When an engine misfire occurs, it's necessary to inspect the ignition system, which mainly consists of spark plugs and ignition coils. Spark plugs are wear-and-tear components that require regular replacement. Prolonged use can lead to increased electrode gap, which affects the spark plug's ignition performance.
