Saab: Saab 93 rotten egg exhaust smell

Saab 93 rotten egg exhaust smell
My wife purchased a 93 back in March and from day one it would emit a sour,
rotten egg smell from under the vehicle. The dealer first said that she had
to ensure that she always used 93 octane gas (she does). When that didn't
make a difference he said she should use the same gas i.e. Sunoco or other
brand but not Mobil (detergent in the gas). When that didn't work he said
it would need 10,000 miles to break in. She has now has over 12,000 miles
and the same smell. The dealer has now said she should drive using the
tiptronic.manual feature on the transmission for a while because it will run
at higher rpms, run hotter and....? I'm getting a bit weary of the bs and
wonering if anyone has an idea. Bad catalytic converter?? something else?
Thanks,

This is how any catalytic converter reacts to petrol with high
contents of sulphur. The sulphur is converted to hydrogen sulphide
(this is the gas that makes rotten eggs smell like rotten eggs) by
the catalytic converter under certain driving conditions. The
problem can be bad gasoline (try a different brand), bad catalytic
converter, broken oxygene sensor, etc.

Re: Saab 93 rotten egg exhaust smell
My vote is for the gas. I'll bet anything you're not using premium
fuel. I had always used premium fuel in everything. Then about 10 -
15 years ago, I read a consumers reports mag. article saying that one
does not need to spend the extra $$$ for premium. So I switched - to
regular Shell in a Mazda that called for 87 octane. Within a tank or
so, I could smell the sulphur. So I switched back to premium, and it
went away.
