Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, cleaning supplies (e.g., MAF cleaner).
  • Disconnect the battery to prevent electrical shorts.
  • Ensure the engine is cool before beginning work.
2. Address Error Codes
  • Use the OBD-II scanner to retrieve and note any error codes.
  • Research the codes to understand the underlying issues that need addressing.
3. Inspect and Replace Spark Plugs
  • Remove the ignition coils using a socket set.
  • Take out the spark plugs with a spark plug socket.
  • Inspect for wear or fouling; replace if necessary.
  • Torque new spark plugs to the manufacturer’s specifications (typically 15-20 Nm).
4. Clean MAF Sensor
  • Locate the MAF sensor connected to the air intake.
  • Carefully disconnect the electrical connector and remove the sensor.
  • Spray MAF cleaner onto the sensor element and allow it to dry.
  • Reinstall the sensor and reconnect the electrical connector.
5. Check Fuel Pressure
  • Attach the fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position (do not start the engine) to check pressure.
  • Compare the reading to manufacturer specifications; replace the fuel pump if pressure is low.
6. Reconnect Battery and Test
  • Reconnect the battery.
  • Start the engine and monitor for roughness or other issues.
  • Clear any fault codes and check if the check engine light reappears.
