Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Gather necessary personal protective equipment (gloves, safety glasses).
2. Address Fault Codes
  • Use the OBD-II scanner to retrieve and note down all trouble codes.
  • Research the codes to determine the relevant systems and components needing attention.
3. Inspect and Replace Components
  • Gas Cap:
    • Inspect for cracks or wear; replace if necessary.
  • Vacuum Hoses:
    • Check for frays or disconnections; replace damaged hoses as needed.
  • Ignition System:
    • Remove spark plugs and inspect for wear; replace if worn.
    • Test ignition coils with a multimeter, replacing any that are out of specifications.
4. Conduct Further Testing
  • If misfires are present, perform a compression test on the cylinders to check for internal engine issues.
  • For fuel system issues, test fuel pressure using a fuel pressure gauge; replace fuel filter or pump if necessary.
5. Reassemble and Reset
  • Reconnect any removed components and hoses.
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear the trouble codes and reset the check engine light.
