You said that the rotten egg smell is the by product of platinum catalytic conversion process..

Plantium is one of the better catalyses for the process of CO to CO2, basically speed up the process. I haven't really smell what you were describing, but usually I walk away from my car right away after a drive.

the previous two responses are dead right -- a good catalytic converter will use platinum to convert CO to CO2. my experience has been that in the beginning, there is more sulpherous "burn-off" than after the car has been run a bit, been broken-in. some catalytic converters have been notorious for poor design and the resulting crappy smell, the most notable of which was the mid- to late-'80s taurus.

anyhow, my .02.

yeah, there was a smell when i press hard acceleration..
i think mainly because the car is brand new, i don't smell that anymore when it has more than 1,000 miles...

I am ignorant of this topic but,
I have heard that people say one on the reasons to that smell was because of the type of gas you are using...If that is true, Wait till your tank of gas is empty and put in a different brand of gasoline.
