02_Q45_Slight smell of rotten eggs?

[Superkwan]

I'm smelling a slight odor of rotten eggs after parking my '02 Q45 after driving several miles? It's not too strong but noticeable...
Could it be my 02 sensors?
Anyone had a similar issue before?
Thanks!

Are you using Tier 1 Premium gas? Check the battery for leaks as it can also produce rotten egg smell.

A rotten egg smell is usually due to clogged/failing catalytic converter or rich fuel mixture. How's your gas mileage. A failing O2 sensor may cause the ECU enrich the fuel-air mixture.Is the CEL on? Have a free scan from Autzone and the likes and get a printout of trouble code, if any.

-- I agree, sounds like a catalytic converter...

This is a classic symptom of a bad catalytic converter.

If you are under 80k miles it should be under warranty for emissions and computer. 80k miles and or 8years warranty, you are almost 8 years but it should start on in-service date of car not manufacturer date.

I have had my 2 cats replaced under warranty already at 60 k miles. My car was a Corporate lease before i bought it, they ight have been putting cheap gas on it.
