Langley Asks: When Should I Replace My Spark Plugs?

Spark plugs might be small, but you will definitely notice if they stop working because the engine will fail to ignite altogether. But barring that happening, how often should you replace them?

Other than the worst-case scenario, you may notice that it is more difficult to get your car started. The check engine light could also illuminate, or you might be getting poor gas mileage – all of these are potential signs of worn-out spark plugs.

Your vehicle might also produce rough engine idling noises when you are stopped at red lights, or it may accelerate slower than it usually does, as well. Even if none of these signs pop up, if you notice the odometer ticking closer to around 130,00 kilometres, that is also a sign to get your spark plugs checked.

Now that you know some signs of worn-out spark plugs schedule a checkup today with us at Willowbrook Chrysler.
