Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the negative battery terminal to ensure safety.
2. Clean Throttle Body
  • Remove the air intake duct connected to the throttle body using a socket set.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Reattach the air intake duct and ensure all clamps are secure.
3. Inspect and Clean the Idle Air Control Valve (IACV)
  • Locate the IACV, typically mounted on or near the throttle body.
  • Detach any electrical connectors and remove the IACV using a socket set.
  • Clean the IACV with appropriate cleaner and inspect for wear.
  • Reinstall the IACV and reconnect electrical connectors.
4. Test and Adjust Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail's test port.
  • Turn the ignition to the "ON" position (do not start) to check fuel pressure.
  • If the pressure is below specifications, inspect the fuel pump and filter for clogs or failures.
5. Inspect Vacuum Lines
  • Visually inspect all vacuum lines for cracks, breaks, or disconnections.
  • Replace any damaged vacuum hoses with new ones.
  • Ensure all connections are tight to prevent vacuum leaks.
6. Check Spark Plugs and Ignition Coils
  • Remove the ignition coils using a socket set.
  • Inspect the spark plugs for wear or fouling; replace if necessary.
  • Reinstall the ignition coils, ensuring they are seated properly.
