smelly exhaust

[lifespeed]

You know that nasty sulfur rotten egg smell you get before your exhaust and engine has warmed up? I am starting to notice I get that even when the car is warm. :(

Is this an indication of shot catalytic converters? The car has 125K miles, Lidio tune, and 02 sensors with less than 20K miles. Runs smooth. Spark plugs have 70K miles so should probably get changed soon, but no misfires.

If the cats loose their effectiveness, then the OBDII catalytic monitor will give you a Check Engine light. If you aren't getting that, ignore. Could be higher sulfur content in the fuel right now. New plugs after 70k is a good idea though.
