  3. Replace Faulty Oxygen Sensors:

    • Install new sensors in the reverse order of removal.
    • Ensure they are tightened to manufacturer specifications.

  4. Perform Engine Repairs (if needed):

    • Depending on the findings from the compression test, repair or replace parts (head gasket, valves, etc.).

  5. Align Wheels (if necessary):

    • Take the vehicle to a professional alignment shop or perform an alignment using appropriate alignment tools.

  6. Educate on Fuel Efficiency:

    • Discuss with the owner the importance of regular maintenance and fuel-efficient driving habits.
