Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to ensure safety during the procedure.
2. Spark Plug Replacement
  • Remove the engine cover if necessary.
  • Use a socket set to remove the spark plug wires.
  • Carefully unscrew and remove each spark plug using a spark plug socket.
  • Inspect the old spark plugs for wear; replace with new plugs of the manufacturer's specification.
  • Reinstall the spark plug wires securely.
3. Air Filter Replacement
  • Locate the air filter housing.
  • Release the clips or screws securing the housing cover.
  • Remove the old air filter and inspect for dirt and clogs.
  • Install a new air filter, ensuring it fits securely in the housing.
  • Reattach the housing cover and secure it.
4. Fuel Injector Cleaning
  • If injectors are found to be clogged, remove them from the fuel rail (follow manufacturer guidelines for this step).
  • Use a fuel injector cleaning kit to clean the injectors or replace them if they are damaged.
  • Reinstall the cleaned or new injectors, ensuring O-rings are lubricated and seated properly.
5. Idle Air Control Valve Inspection
  • Locate the idle air control valve (IAC) on the throttle body.
  • Disconnect the electrical connector and remove the IAC using the appropriate socket.
  • Clean the valve with throttle body cleaner to remove carbon buildup.
  • Reinstall the IAC and reconnect the electrical connector.
