Faulty O2 sensor could cause the car to run rich or lean, but would not really explain any significant sulfur smell in the exhaust. Could be that you did get a heavy dose of sulfur in your gas & it fouled the sensor as it burned off. Is the dealer replacing the sensor for you? If so, I would be certain to use a high quality gas for the next few tanks so as to dilute that sulfur as much as possible- no convenience store/el cheapo gas, regardless of the octane rating . (I recommend never using the cheap stuff if you have a choice, but hey, to each his own)

It's probably been said around here before, but it's also best not to fill up while the tanker is dumping its load into the tanks. If properly maintained, all pumps should have high quality filters that will stop sediment & water from getting into your gas tank, but why take the chance? I know of several stations in my area that have been caught bypassing the filters rather than paying to replace them when they get clogged.

No I fill up 92 everytime, at the same station, same pump, everytime. I also know about the not filling up while a tanker is there, thing. So I always avoid pumping anytime near its pump into the station tanks. The dealership is replacing it though which is good, and really is what they are supposed to do.

my 1st o2 is the only 1 hanging in the dp. th second has the plug defowler so its not even really in harms way. ill have to run the code once my ap comes in. i might be buying a new set of plugs. eh....could be a lot worse.

it was the first sensor on mine, so its possible
