Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to ensure safety.
2. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Reassemble the air intake duct securely.
3. Replace Fuel Filter (if applicable)
  • Locate the fuel filter (consult the owner's manual for exact location).
  • Release fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
  • Disconnect the fuel lines from the filter using appropriate wrenches.
  • Install the new fuel filter, ensuring the flow direction matches the markings.
  • Reconnect the fuel lines and reinsert the fuel pump fuse.
4. Replace Spark Plugs
  • Remove the ignition coils by unbolting and disconnecting the electrical connectors.
  • Unscrew and remove the old spark plugs using a spark plug socket.
  • Check the gap on the new spark plugs and adjust if necessary.
  • Install the new spark plugs and torque to the manufacturer’s specification (usually around 20-25 Nm).
  • Reinstall the ignition coils.
5. Check and Clean MAF Sensor
