What is engine misfire?

Engine misfire refers to a condition in which the combustion process fails to occur in one or more of the engine's cylinders, disrupting the normal operation of the engine. This misfiring can lead to a variety of symptoms, such as rough idling, loss of power, decreased fuel efficiency, and increased exhaust emissions. When an engine misfires, it may indicate underlying issues like faulty spark plugs, problems with fuel delivery, or issues with the ignition system. Understanding this definition is crucial for diagnosing engine performance problems and can help in implementing appropriate fixes.
