Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Clean or Replace the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body, removing any carbon deposits.
Reinstall the air intake duct and ensure all connections are secure.

3. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench
Remove the ignition coils from the spark plugs by unscrewing them.
With a socket, remove the spark plugs from the engine.
Inspect the spark plugs for wear; if damaged, replace them with OEM-spec plugs.
Torque the new spark plugs to the manufacturer-recommended specification.
Reinstall the ignition coils.

4. Check and Replace Fuel Filter (if applicable)

Tools Required: Fuel line disconnect tool, socket set
Locate the fuel filter and disconnect the fuel lines using the fuel line disconnect tool.
Remove the fuel filter and replace it with a new one.
Reconnect the fuel lines and check for any leaks.

5. Inspect and Replace MAF Sensor (if necessary)
