200q20v Odd Smells and Noises

[Andrew Lundy]

Sulfur smell....causes I've found:  Bad gas, bad cat, bad O2 sensor, bad
knock sensor!!

If mum used a gas station that she doesn't "frequent" you could right it off
to bad gas.  You could also double check the knock sensors (and torque's).
Check the O2 sensors if the mileage is appropriate!!  Check the cat last!!

Sounds like "bad" gas to me....may have been just a touch "watered" down!!

My $.02...HTH!!
