5 of 5 Check Engine Light
Replace Spark Plugs and Wires
The spark plug seals the combustion chamber and provides a gab for a spark to jump across and initiates combustion in your engine. When the plugs are failing, the spark plugs misfire. You’ll feel a little jolt in your car’s acceleration when this happens.
What causes it: Most spark plugs in cars from before 1996 should be replaced every 25,000-30,000 miles. Newer ones can last up to 100,000 miles. Still, plugs fail over time and there’s not much you can do about it.
What you should do: Get them replaced right away. It’s easy and cheap and your car will run better for it. If your spark plugs fail and you’ve made your way to the auto parts store, you can replace them easily following the video above. Since this is part of your vehicles regular maintenance, the spark plugs are usually easily accessible from the hood of the car. It’s simple enough that I’ve seen people doing this in the auto parts parking lot on several occasions.
Plenty of other possibilities for a check engine light are out there, but the above five are the most common. How long do you usually let the check engine light stay on before you do something about it?
