Can Old Spark Plugs Be the Cause of Lit Check Engine Light?

Can Old Spark Plugs Be the Cause of Lit Check Engine Light

Spark plugs may be small in size, but they have a super important responsibility when it comes to your vehicle. These small metal pieces facilitate the spark that starts up the combustion process. Without them, you will not be able to start your car. Spark plugs also put your engine's pistons in motion, which is necessary to achieve a precise air-fuel mixture.

 

If you get into your car, truck, or SUV and find that your engine won't start, you may naturally believe it is a battery problem. However, the culprit could very well be faulty spark plugs. If you can't start your car and notice the check engine light on, then you're probably dealing with bad spark plugs. 

 

Old spark plugs can cause your vehicle's check engine light to light up. Besides the infamous yellow dashboard light, you may also notice various troubling signs:

  • Engine misfires
  • Rough idling
  • Problems accelerating
  • Trouble starting your vehicle
  • Increased exhaust emissions
  • Poor fuel efficiency
  • Overall inadequate vehicle performance
