- 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 replaced catalyst, are likely to have a sulfur smell due to the highly active state of new catalysts. Replacing the catalyst can actually make the symptom worse.
