Smell from 97 Maxima
#1
You know that car new cars have when going fast or up a hill? That sulfur like smell from the Cat Converter? I bought a used 97 SE w/ 41K miles on it, 5spd, loaded. I know it once had a RT CAT on it, but I'm unsure if it still does. I would think at 41K miles I wouldn't have that sulfur smell. Anyone else have this, or do you think it's because the cat is RT or maybe since the stock CAT hasn't been run in a while. The smell is VERY evident too.

an over-rich fuel mixture. A faulty oxygen sensor or defective fuel
injectors could cause the rich mixture. Also consider anything which
prevents the engine controls from going into closed-loop mode. This would
include a faulty Engine Coolant Temperature Sensor or a thermostat which is
stuck open, preventing the engine from reaching normal operating
temperature.
