Answer 1

Excessive sulfur smell in the exhaust with a catalytic converter can be an indication of a rich fuel mixture.

Step-by-step explanation:

An excessive sulfur smell in the exhaust with a catalytic converter can be an indication of a rich fuel mixture. When the fuel mixture is too rich, it means that there is an excess of fuel being injected into the combustion chamber. This can cause incomplete combustion of the fuel, resulting in the release of sulfur compounds.
