Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface with the engine off and cooled down.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Replace Air Filter
  • Locate the air filter housing.
  • Open the housing and remove the old air filter.
  • Install a new, clean air filter, ensuring it fits snugly in the housing.
  • Secure the housing cover back in place.
3. Clean Throttle Body
  • Remove the intake duct connected to the throttle body.
  • Use a throttle body cleaner and a soft cloth to clean the inside of the throttle body.
  • Ensure the throttle plate moves freely; if necessary, gently open it while cleaning.
  • Reattach the intake duct securely.
4. Replace Fuel Filter (if applicable)
  • Locate the fuel filter (refer to the service manual for exact location).
  • Relieve fuel system pressure before removal.
  • Disconnect fuel lines from the filter using appropriate tools.
  • Install the new fuel filter, ensuring the flow direction is correct as marked on the filter.
  • Reconnect the fuel lines securely.
5. Replace Spark Plugs
  • Remove the ignition coil or spark plug wires to access the spark plugs.
  • Using a spark plug socket, remove old spark plugs.
  • Check the gap on the new spark plugs and adjust if necessary.
  • Install the new spark plugs with specified torque (typically around 15 lb-ft).
  • Reattach the ignition components.
