Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect and Replace Spark Plugs
  • Tools Required: Socket set, torque wrench
  • Remove the engine cover (if applicable).
  • Disconnect the ignition coil connectors.
  • Remove the ignition coils using a socket.
  • Unscrew and remove the old spark plugs using a spark plug socket.
  • Inspect spark plugs for signs of wear; replace with OEM spark plugs if necessary.
  • Torque the new spark plugs to the manufacturer's specification (typically around 13-16 lb-ft).
  • Reinstall ignition coils and reconnect connectors.
3. Test and Replace Fuel Injectors (if necessary)
  • Tools Required: Fuel pressure gauge, injector cleaner kit
  • Connect a fuel pressure gauge to check the fuel pressure against manufacturer specifications (typically between 30-50 psi).
  • If pressure is low, clean or replace fuel injectors using an injector cleaner kit.
  • If injectors are faulty, replace with OEM components.
4. Inspect Intake and Vacuum Lines
  • Visually inspect all intake hoses and vacuum lines for cracks, leaks, or disconnections.
  • Replace any damaged hoses with OEM replacements.
  • Ensure all connections are tight and secure.
5. Check Exhaust System and Catalytic Converter
  • Inspect the exhaust system for any visible leaks or damage.
  • Use a vacuum gauge to check for back pressure in the exhaust; the reading should be low.
  • If back pressure is high, consider replacing the catalytic converter.
6. Reconnect Battery and Clear Codes
  • Reconnect the battery terminals.
  • Use the OBD-II scanner to clear any error codes.
  • Start the engine and ensure the check engine light remains off.
