Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface.
  • Disconnect the battery to prevent electrical issues during repairs.
2. Address Faulty Spark Plugs and Ignition Coils
  1. Remove the engine cover (if applicable) using a socket set.
  2. Disconnect the ignition coil connectors and remove the bolts holding the coils.
  3. Replace any damaged spark plugs with OEM parts (torque to specifications).
  4. Reinstall the ignition coils and reconnect the connectors.
3. Clean or Replace the MAF Sensor
  1. Locate the MAF sensor on the intake manifold.
  2. Disconnect the electrical connector and remove the sensor.
  3. Clean the MAF sensor using MAF cleaner; do not touch the sensor wire.
  4. Allow it to dry completely before reinstalling.
4. Inspect and Clean Fuel Injectors
  1. Access the fuel rail by removing engine cover bolts and any necessary components.
  2. Disconnect the fuel lines with a fuel line removal tool (use caution as fuel may escape).
  3. Clean the fuel injectors using a fuel injector cleaning kit or replace them if necessary.
  4. Reconnect the fuel lines and ensure they are secure.
5. Recheck and Clear Codes
  1. Reconnect the battery and start the engine.
  2. Use the OBD-II scanner to clear any stored fault codes.
  3. Monitor the engine while accelerating to verify the check engine light does not illuminate again.
