Many Subaru owners do everything they know when it comes to maintaining their vehicle except to change the spark plugs. Spark plugs are easy to overlook. Most of the time, they simply ignite the air-fuel mixture in the combustion engine that makes your vehicle run, and we don't give them a second thought. Because of the role they perform, they must be in good condition all the time, otherwise your vehicle’s engine might not function properly.
Signs your Subaru spark plugs need replacement
Here are the top signs that indicate spark plugs may have reached the end of their life:
- Check engine light comes on
If your spark plugs are failing, you Subaru’s onboard computer will turn on the check engine light. You may also notice engine misfires.
A telltale sign that your spark plugs are bad is when you experience troubles starting your Subaru. Since this component is responsible for providing the spark that ignites fuel in the engine and gets it running, any problem with it will affect the normal functioning of your engine.
Not only will your vehicle have to work harder to start but it will also struggle to deliver a great performance. Faulty or worn spark plugs can throw the engine off, making it difficult for it to effectively burn fuel.
Since faulty spark plugs are unable to do their job properly, every process that relies on their functioning will also be affected, including your Subaru’s ability to accelerate at a normal rate.
