Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, multimeter, vacuum gauge, smoke machine.
  • Ensure the vehicle is parked on a level surface with the engine off and cool.
2. Address Error Codes
  • Use the OBD-II scanner to pull diagnostic trouble codes (DTCs).
  • Research the codes to determine potential causes and components involved.
3. Inspect and Replace Components
  • Ignition System:

    • Remove engine cover (if applicable) using a socket set.
    • Replace worn spark plugs with OEM replacements, tightening to manufacturer's specifications (typically 12-15 lb-ft).
    • Check ignition coils for proper function; replace any faulty coils.
  • Fuel System:

    • Connect a fuel pressure gauge to the fuel rail.
    • Start the engine and check for proper fuel pressure (refer to service manual for specifications).
    • If low, inspect the fuel filter and fuel pump for blockages or failures.
  • Vacuum Leaks:

    • Use a smoke machine to identify leaks in vacuum hoses and gaskets.
    • Replace any damaged hoses or gaskets found during inspection.
4. Clear Codes and Test
  • After completing repairs, reconnect the OBD-II scanner.
  • Clear the check engine light codes and take the vehicle for a test drive to ensure the issue is resolved.
