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.Originally posted by chromaplast:
what is "platinum catalytic conversion process."
You said that the rotten egg smell is the by product of platinum catalytic conversion process..
what is that?
( just wondering because I had that smell again after going 90mph on the highway today)
