Signs That Spark Plugs Need Replacing
Even if you haven't reached the recommended mileage, there are some signs that may indicate your Lexus IS350's spark plugs need to be replaced, such as:
- Decreased Fuel Efficiency: Worn spark plugs can cause the engine to run less efficiently, leading to a noticeable drop in fuel economy.
- Rough Idling or Misfiring: Faulty spark plugs can cause the engine to misfire, resulting in a rough or uneven idle.
- Difficulty Starting: Worn spark plugs may struggle to ignite the air-fuel mixture, making it harder to start the engine.
- Check Engine Light: The vehicle's onboard diagnostics system may detect issues with the spark plugs, triggering the check engine light.
If you notice any of these symptoms, it's best to have your Lexus IS350 inspected by a qualified technician to determine if the spark plugs need to be replaced.
