Solution
1. Preparation
  • Gather tools including an OBD-II scanner, socket set, torque wrench, and safety glasses.
  • Disconnect the negative battery terminal to ensure safety during repairs.
2. Address Fault Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Record all trouble codes and research the corresponding issues.
  • Clear the codes and take the vehicle for a test drive to see if any codes reappear.
3. Replace Faulty Components
  • Spark Plugs and Ignition Coils:
    • Remove engine cover if necessary.
    • Disconnect electrical connectors from ignition coils and remove them using a socket.
    • Replace spark plugs using a torque wrench to the manufacturer's specifications (typically around 13-15 lb-ft).
  • Air Filter Replacement:
    • Open the air intake housing by unscrewing the clamps.
    • Remove the old air filter and install a new one, ensuring a snug fit.
  • Fuel System Check:
    • Use a fuel pressure gauge to check for proper pressure at the fuel rail.
    • Replace any faulty fuel injectors using the appropriate tools and procedures.
4. Inspect and Repair Exhaust System
  • Visually inspect the exhaust system for signs of damage or corrosion.
  • If a blockage is detected, remove and clean the catalytic converter or replace it if necessary.
