Reattach the air filter housing cover and tighten the screws or bolts securely.

3. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth or brush.
Remove the intake duct connected to the throttle body.
Spray throttle body cleaner onto a soft cloth or directly inside the throttle body.
Gently scrub the throttle plate and surrounding areas to remove carbon buildup.
Reinstall the intake duct and ensure it is secured properly.

4. Inspect and Replace Spark Plugs

Tools Required: Socket wrench set, torque wrench.
Remove the ignition coils by disconnecting the electrical connectors and unbolting them.
Take out the old spark plugs using a spark plug socket.
Check the gap on the new spark plugs and adjust if necessary.
Install new spark plugs and torque them to the manufacturer's specifications (typically 15-20 lb-ft).
Reinstall the ignition coils and reconnect the electrical connectors.

5. Check and Replace Fuel Filter (if applicable)

Tools Required: Fuel line disconnect tool, wrench set.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
