Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Disconnect the negative terminal of the battery to ensure safety.
  • Allow the engine to cool completely if it has been running recently.
2. Inspect and Replace Spark Plugs
  • Remove the engine cover (if applicable) using a socket set.
  • Use a spark plug socket to remove each spark plug one at a time.
  • Inspect for wear or fouling and replace with OEM or equivalent spark plugs, ensuring they are gapped correctly.
  • Torque the new spark plugs to the manufacturer's specifications (typically around 15-20 Nm).
3. Fuel System Service
  • Remove the fuel pump fuse to relieve fuel pressure.
  • Disconnect the fuel line from the fuel rail and check for leaks.
  • Replace the fuel filter if it shows signs of clogging.
  • Reconnect the fuel line and replace the fuse.
4. Clean the Idle Air Control Valve (IAC)
  • Locate the IAC valve, usually near the throttle body.
  • Remove the IAC valve by disconnecting the electrical connector and unscrewing the mounting bolts.
  • Clean the valve using carburetor cleaner and a soft brush.
  • Reinstall the IAC valve and reconnect the electrical connector.
5. Reassemble and Test
  • Reinstall any components that were removed for access.
  • Reconnect the negative battery terminal.
  • Start the engine and allow it to reach operating temperature.
