Solution

1. Preparation

Tools Required: Socket set, torque wrench, screwdrivers, OBD-II scanner, spark plug socket, fuel line removal tool, safety glasses, gloves.
Disconnect the battery to ensure safety during the process.

2. Replace Spark Plugs

Remove the ignition coil by unscrewing the bolts and disconnecting the electrical connector.
Use the spark plug socket to remove old spark plugs; inspect for wear.
Install new spark plugs by hand to avoid cross-threading, then torque to the manufacturer’s specifications (typically around 13-16 lb-ft).
Reattach the ignition coil securely.

3. Replace Air Filter

Open the hood and locate the air filter housing.
Remove the clips or screws securing the housing cover.
Take out the old air filter and replace it with a new one, ensuring a snug fit.
Reattach the housing cover and secure it.

4. Replace Fuel Filter (if applicable)

Locate the fuel filter; it may be under the vehicle or in the engine bay.
Relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines using a fuel line removal tool.
Remove the old fuel filter and replace it with a new one, ensuring correct orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

5. Inspect Other Components

Check the engine oil level and condition; change oil if necessary.
Inspect belts and hoses for wear and replace as needed.
Verify that all connections are secure and there are no visible leaks.
