Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, torque wrench, flashlight, and safety goggles.
Safety Precautions: Ensure the vehicle is parked on a level surface, with the engine off and cool before starting work.

2. Address Exhaust Leaks

Lift the Vehicle: Use a jack and jack stands to safely elevate the vehicle if necessary.
Inspect the Exhaust System: Visually check for holes, rust, or loose connections in the exhaust pipes and muffler.
Tighten Loose Connections: If any bolts or clamps are loose, use a torque wrench to tighten them to manufacturer specifications.
Seal Small Leaks: If small leaks are found, use exhaust tape or epoxy sealant to temporarily fix them. For larger issues, replacement parts may be needed.

3. Replace Spark Plugs (if necessary)

Remove Engine Cover: Use a socket set to remove any screws or bolts securing the engine cover.
Disconnect Ignition Coils: Carefully unplug the ignition coils from the spark plugs.
Remove Old Spark Plugs: Use a spark plug socket to unscrew the old spark plugs.
Install New Spark Plugs: Apply anti-seize compound to the threads of the new spark plugs and install them, tightening to the manufacturer’s torque specifications.
Reconnect Ignition Coils: Plug the ignition coils back into place and replace the engine cover.
