If a spark plug does not ignite, the engine will fail to start or run efficiently, leading to misfires, rough idling, and decreased performance. This failure can result from issues such as a worn-out spark plug, faulty ignition system, or fuel delivery problems. As a consequence, the vehicle may experience increased emissions and potential damage to the engine over time. Regular maintenance and timely replacement of spark plugs are essential to ensure optimal engine performance.
