- Exhaust System Concerns: Odor (Sulfur or Rotten Egg Smell)

NOTE: A slight sulfur smell may be normal. Catalysts with less than 8,000-16,000 kilometers (5,000-10,000 miles) (new vehicle or catalyst) are likely to have a sulfur smell due to the highly active state of new catalysts. Installing a new catalyst may actually make the symptom worse.

Fuel Source	Talk with the customer. Since sulfur content can vary in different fuels, suggest trying a different fuel source.
