What Are Some Common Signs That Indicate it’s Time for Spark Plug Replacement?
Some common signs that indicate it’s time for spark plug replacement include:

- Rough Idling: A rough or shaky idle can be a sign that the spark plugs are not firing correctly, causing uneven engine performance. This can be particularly noticeable when the vehicle is stopped but the engine is still running.
- Increased Emissions: Worn spark plugs can lead to incomplete combustion, which may result in higher levels of emissions from the exhaust. If your vehicle fails an emissions test, it may be time to check and replace the spark plugs.
