  • Remove the air intake duct leading to the throttle body.
  • Spray throttle body cleaner into the throttle body and wipe with a soft cloth.
  • Reinstall the air intake duct securely.
3. Replace Spark Plugs and Ignition Coils (if necessary)
  • Tools Required: Socket set, torque wrench
  • Remove the ignition coil cover (if applicable).
  • Disconnect the electrical connectors from the ignition coils.
  • Remove the bolts securing the ignition coils and pull them out.
  • Replace the spark plugs using a socket wrench, ensuring to torque them to the manufacturer's specifications.
