  • Disconnect the battery to ensure safety while working on the vehicle.
2. Inspect and Repair Exhaust System
  • Tools Required: Wrench set, exhaust pipe cutter, gasket scraper, sealant
  • Check for leaks in the exhaust pipes, muffler, and catalytic converter:
    • Visually inspect for holes or cracks.
    • Use a smoke test if needed to locate leaks.
  • If leaks are detected, cut out the damaged section and replace it:
    • Use the exhaust pipe cutter to remove the damaged portion.
    • Install new exhaust sections, ensuring proper alignment and sealing with exhaust gaskets.
    • Tighten connections to manufacturer specifications.
3. Check and Replace Catalytic Converter (if necessary)
  • Tools Required: O2 sensor socket, wrench set
  • If the catalytic converter is faulty:
    • Remove the oxygen sensors using an O2 sensor socket.
    • Unbolt the catalytic converter from the exhaust pipes.
    • Install a new catalytic converter, ensuring it fits securely and is properly aligned.
    • Reinstall oxygen sensors.
4. Inspect and Replace Spark Plugs
  • Tools Required: Spark plug socket, torque wrench
  • Remove old spark plugs:
