Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to ensure safety during repairs.
2. Replace Fuel Filter
  • Locate the fuel filter (usually along the fuel line).
  • Use a socket set to remove the mounting brackets.
  • Disconnect the fuel lines carefully to prevent spilling fuel.
  • Install the new fuel filter in the same orientation as the old one.
  • Reconnect the fuel lines securely and reattach the mounting brackets.
3. Replace Spark Plugs and Ignition Coils
  • Remove the engine cover (if applicable) using a socket set.
  • Disconnect the ignition coil connectors and remove the bolts holding the coils in place.
  • Take out the old spark plugs using a spark plug socket, ensuring no debris falls into the cylinder.
  • Install new spark plugs with the correct gap specification (typically 0.030 inches).
  • Reinstall the ignition coils and reconnect the connectors.
4. Clean Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
  • Ensure the throttle plate moves freely and does not stick.
  • Reattach the air intake duct securely.
5. Reconnect Battery
  • Reconnect the battery terminals and ensure they are tight.
