What are the symptoms of engine misfire?

[DeLeilani]

Symptoms of engine misfire: 1. Abnormal engine operation or insufficient power; 2. Uneven operation with rhythmic shaking; 3. Black smoke from the muffler. Hazards of misfire: 1. Decreased engine lubrication; 2. Increased fuel consumption and emission pollution; 3. Accelerated wear of moving parts and increased abnormal shaking. Engine misfire can lead to high fuel consumption, black smoke, lack of power, decreased horsepower, inability to accelerate, severe shaking, increased driving noise, and poses significant safety risks, especially on uphill starts where the engine load increases, making the body shake more noticeably and prone to sudden stalling.
