What does an engine misfire typically indicate?

An engine misfire typically indicates that one or more cylinders are not igniting properly. A misfire occurs when the air-fuel mixture in a cylinder fails to ignite at the appropriate time or does not ignite at all. This can result from various issues, such as faulty spark plugs, ignition coils, fuel injectors, or even problems with the engine's timing. When a cylinder misfires, it disrupts the smooth operation of the engine, possibly causing it to shake or vibrate and may trigger the check engine light on the dashboard. Addressing the underlying cause of the misfire is crucial to ensure optimal engine performance and efficiency.
