Tools Required: Throttle body cleaner, screwdriver, cleaning cloth.
Steps:
1. Locate the throttle body by following the air intake duct.
2. Remove the air intake duct clamps and detach it from the throttle body.
3. Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body to remove carbon deposits.
4. Reattach the intake duct and secure it with clamps.

3. Replace Spark Plugs

Tools Required: Socket set, torque wrench, gap gauge.
Steps:
1. Remove the ignition coil covers (if applicable) by unscrewing them.
2. Disconnect the ignition coils from the spark plugs.
3. Using a socket, remove the spark plugs from the engine.
4. Check the gap on the new spark plugs using a gap gauge and adjust if necessary.
5. Install the new spark plugs and torque them to the manufacturer's specifications.
6. Reconnect the ignition coils and reinstall the covers.

4. Check and Replace Fuel Filter (if applicable)

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