Warning signs it’s time to replace your vehicle’s spark plugs
Spark plugs are essential for your engine to start and for your car to run smoothly and efficiently. Old or worn spark plugs can cause your engine to knock and misfire, resulting in disastrous and costly consequences. Here are four signs that it’s time to replace your vehicle’s spark plugs.
The check engine light is on
Your car’s internal diagnostic system will detect if your vehicle misfires, which indicates a possible spark plug problem. Misfires put tremendous stress on your engine and catalytic converter, leading to expensive repairs. If your check engine light is on, don’t ignore it.
Your car doesn’t accelerate well
Your car needs a lot of power to speed up, and misfiring spark plugs rob your engine of energy, making it more difficult to accelerate. If your car jerks or stutters while accelerating or going up a hill, it could mean your engine is misfiring, and it’s time to get your plugs checked.
You hear strange noises
If you hear rattling or knocking sounds as your engine idles, it’s probably misfiring. It’s best to get your vehicle checked by a professional.
You visit the gas station more often
Old and worn spark plugs can reduce fuel efficiency by as much as 30 per cent because they don’t effectively burn the gas going into the engine. Many things can cause decreased fuel efficiency, and faulty spark plugs are one.
Your car won’t start
Your spark plugs are part of your car’s ignition system. If you turn the key and the plugs fail to spark, your engine won’t start. Regardless of the cause, it’s time for a mechanic when your car is dead.
The owner’s manual says so
Most manufacturers recommend replacing spark plugs every 50,000 kilometres, but spark plug quality varies. Some last around 130,000 kilometres, while cheap plugs made of copper may last approximately 40,000 kilometres. “Extended life” spark plugs made of more resilient metals can last up to 160,000 kilometres.
Benefits of replacing old or worn spark plugs
Getting your spark plugs replaced has numerous benefits to your vehicle, including:
- Consistent, efficient combustion
- Better fuel efficiency
- Dependable and quick starts
- Lower emissions
Ensure your next tune-up includes a spark plug check.
