- 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), either from a new vehicle or new 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.
