Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface with the engine off and cool.
  • Disconnect the battery to prevent any electrical shorts during work.
2. Address Engine Issues

  1. Check and Replace Air Filter

    • Remove the air filter cover using a screwdriver.
    • Inspect the air filter; replace it if it appears dirty or clogged.
    • Reinstall the cover securely.

  2. Change Engine Oil

    • Drain the old engine oil using a wrench to remove the oil drain plug.
    • Replace with new oil of the manufacturer-specified type and viscosity.
    • Change the oil filter to ensure no contaminants are present.
3. Repair Exhaust System

  1. Inspect Exhaust Components

    • Check for any rust or damage on the exhaust pipes, catalytic converter, and muffler.
    • If any components are damaged, remove them using a socket set and replace with new parts.

  2. Seal Any Leaks

    • Use exhaust sealant for minor leaks or replace gaskets if necessary.
    • Tighten all connections to ensure a proper seal.
4. Final Checks
  • Reconnect the battery.
  • Start the engine and let it idle to check for any leaks or unusual sounds.
  • Ensure the check engine light is off after a few minutes of operation.
