• Poor Fuel Economy: Worn or faulty spark plugs can cause incomplete combustion, resulting in increased fuel consumption as the engine works harder to maintain performance.
• Difficulty Starting the Engine: If the spark plugs are worn, the engine may struggle to start due to insufficient spark being generated, leading to prolonged cranking times.
• Rough Idling: A healthy engine should idle smoothly; however, failing spark plugs can cause irregular combustion, leading to a shaky or unstable idle.
• Check Engine Light: The check engine light may illuminate due to various issues, including spark plug failure, which can be diagnosed through an OBD-II scanner.

Engine misfires are a clear sign that the spark plugs are not functioning correctly. This can lead to a noticeable decrease in engine power and can also cause increased wear on engine components over time.

Poor fuel economy is another symptom that can indicate spark plug issues. When spark plugs wear out, they can lead to incomplete combustion, causing the engine to consume more fuel than necessary.

Difficulty starting the engine can be frustrating and is often a result of failing spark plugs. If the spark plugs are not providing a strong enough spark, the engine may require multiple attempts to start, which can be particularly problematic in cold weather.

Rough idling can be attributed to inconsistent spark delivery from worn spark plugs. This can lead to a jerky or vibrating sensation while the car is stationary, indicating that the engine is not running smoothly.

Finally, the check engine light may serve as an early warning system for spark plug issues. When the vehicle’s onboard diagnostics detect irregularities in engine performance, it triggers the light, which should prompt a diagnostic check to identify the root cause.
