Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Sub-steps:
1. Remove the air intake duct to gain access to the throttle body.
2. Disconnect the throttle body electrical connector.
3. Remove the throttle body by unscrewing the mounting bolts.
4. Clean the throttle body with throttle body cleaner and a soft cloth.
5. Reinstall the throttle body and reconnect the electrical connector.
6. Reattach the air intake duct.

4. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench.
Sub-steps:
1. Remove the ignition coils or spark plug wires to access the spark plugs.
