Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, multimeter, exhaust gas analyzer, safety glasses, gloves.
  • Ensure the vehicle is on a level surface and the engine is cool before beginning work.
2. Addressing Exhaust Leaks
  • Sub-steps:
    • Raise the vehicle using jack stands for better access to the exhaust system.
    • Inspect all joints, gaskets, and connections for signs of leaks or damage.
    • If any leaks are found, replace the faulty gaskets or components.
    • Reassemble the exhaust system and tighten all bolts according to the manufacturer specifications.
3. Replacing Contaminated Fluids
  • Sub-steps:
    • If engine oil or coolant is contaminated, drain the affected fluid.
    • Replace with manufacturer-recommended oil and coolant.
    • Check the oil filter and replace if necessary.
    • Run the engine for a few minutes and then check fluid levels again, topping off as needed.
4. Repairing or Replacing Fuel System Components
