Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the battery to ensure safety while working on the electrical components.
2. Clean or Replace Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
  • If heavily damaged, replace the throttle body with a new one.
  • Reconnect the air intake duct securely.
3. Inspect and Clean Idle Air Control Valve
  • Locate the IAC valve (usually at the throttle body).
  • Remove the IAC valve from its mounting.
  • Clean the valve with throttle body cleaner and check for proper operation.
  • If the valve is defective, replace it with a new one.
4. Check Fuel Pressure
  • Attach a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
  • If the pressure is below specification, check the fuel pump and replace if necessary.
5. Inspect MAF Sensor
  • Locate the MAF sensor in the air intake system.
  • Disconnect the electrical connector and remove the sensor.
  • Clean the MAF sensor with MAF cleaner; do not touch the sensing element.
  • Reinstall the sensor and reconnect the electrical connector.
6. Inspect Vacuum Lines
  • Visually inspect all vacuum lines for cracks, disconnections, or wear.
  • Replace any damaged vacuum lines to ensure proper engine operation.
