1. Open the hood of your vehicle.
2. Locate the engine cover, which is a black plastic cover that covers the top of the engine.
3. Remove the engine cover by lifting it up and pulling it towards you.
4. You will see four spark plug wires connected to the top of the engine. Each wire is connected to a spark plug.
5. To remove a spark plug wire, grasp the rubber boot at the end of the wire and pull it straight up. Do not pull on the wire itself, as this could damage it.
6. Once the spark plug wire is removed, you will see the spark plug.
7. Use a spark plug wrench to loosen the spark plug and remove it from the engine.
8. Inspect the spark plug for wear or damage. If the spark plug is worn or damaged, replace it with a new one.
9. Repeat steps 5-8 for the remaining three spark plugs.
10. Once all four spark plugs have been replaced, reinstall the engine cover.
