Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Allow the engine to cool down before working.
2. Inspect and Replace Spark Plugs
  • Remove the engine cover if applicable.
  • Use a spark plug socket to carefully remove the spark plugs.
  • Inspect the spark plugs for signs of wear or carbon build-up. Replace any faulty spark plugs with OEM specifications.
  • Torque new spark plugs to the manufacturer's specifications (typically around 13-16 lb-ft).
3. Test and Replace Ignition Coils
  • Use a multimeter to check the primary and secondary resistance of each ignition coil.
  • If any coils are out of spec, remove and replace them with OEM parts.
  • Reinstall the ignition coils, ensuring they are seated properly.
4. Inspect Fuel Injectors
  • Remove the fuel rail if necessary to access the fuel injectors.
  • Check for clogs or leaks in the injectors; clean or replace as needed.
  • Reinstall the fuel rail and ensure proper torque specifications are followed.
5. Check Air Intake System
  • Inspect the air filter and replace if it is dirty or clogged.
  • Check the intake manifold for leaks and ensure the throttle body is clean and free of debris.
6. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear the trouble codes.
  • Start the engine and check if the check engine light remains off.
