You smell something that smells like sulfur coming from your vehicle?

The sulfur smell is the catalytic converter. There will always be some smell of sulfur. The converter changes the carbon monoxide in the exhaust to sulfur dioxide. Strong sulfur smell may be an indication the converter needs to be changed.

This can also be a symptom of a leaking battery. We had a battery crack, and the sulfur smell was almost overpowering for a couple of days. Even after it was replaced, the smell lingered for a bit.
