What can cause your engine to misfire?

A misfire in an engine occurs when one or more cylinders fail to fire correctly, which can lead to poor engine performance and increased emissions. Faulty spark plugs are a common cause of engine misfires because they are responsible for igniting the air-fuel mixture in the cylinders. If a spark plug is damaged, worn out, or not functioning properly, it can lead to weak or nonexistent sparks, preventing the fuel from igniting effectively.

When the spark plugs are in poor condition, the engine may run unevenly, experience shaking or vibrations, and exhibit a noticeable decrease in power and fuel efficiency. That's why ensuring that spark plugs are in good working condition is essential for the overall performance and reliability of the engine. Regular maintenance, including checking and replacing spark plugs, is vital to avoid misfires and maintain optimal engine function.
