An excessive sulfur smell in the exhaust with a cat can be an indication of:
A
lean fuel mixture
B
vacuum leak
C
rich fuel mixture
D
coolant leaking into combustion chamber
A lean fuel mixture would not cause a sulfur smell; coolant leaking into the chamber would cause a gray exhaust color; a vacuum leak would cause a rough idle that would decrease as engine speed increases.
