The spark plugs have a super important job when it comes to your vehicle. They are the components that cause the spark to start-up combustion which is necessary to start your car. They put your engine's pistons in motion which is also important for proper air-fuel mixture and smooth operation.
If you get into your car and find that your vehicle won't start, you may believe that the issue is with the battery. However, oftentimes, it could be failing spark plugs. So, how do you know if your spark plugs are bad, and do they cause your vehicle's check engine light to turn on?
The answer is - yes! Worn spark plugs can cause your vehicle's check engine light to illuminate, indicating an issue. It may even be a flashing check engine light. This is because bad spark plugs can cause your engine to misfire, which will trigger the check engine light to turn on. Some other symptoms of bad spark plugs include the following:
- Rough idling
- Problems accelerating
- Increased exhaust emissions
- Trouble starting your vehicle
- Bad fuel efficiency
- Overall bad vehicle performance
