1. Remove the air intake duct connected to the throttle body.
2. Spray throttle body cleaner into the throttle body opening.
3. Use a soft brush to scrub away carbon deposits.
4. Wipe clean with a rag and ensure the throttle plate moves freely.
5. Reattach the air intake duct securely.

3. Replace Spark Plugs

Tools Required: Socket set, torque wrench
Steps:
1. Remove the ignition coils or spark plug wires carefully.
2. Use a socket to remove the old spark plugs.
3. Check the gap on new spark plugs and adjust to manufacturer specifications.
4. Install the new spark plugs and torque to the manufacturer’s specifications.
