[s-cars] eggs

[Ulrich L. McKenzie]

Paul,

Had a similar problem with my wife's Passat VR6.  Changed o2 sensors, no
difference.  Started using better gas-big difference.  Turns out that
several oil companies (in Canada) are selling fuel with a higher sulphur
content than recommended by many European car manufacturers.  IIRC Esso is
the worse offender with Shell also on the bad side of acceptable.  Sunoco
received kudos' in all areas of the report.  Can't find the link to it right
now, but if I dig it up I will post to the list.

US experience might be slightly different, but I suspect that the same issue
exists.

Bottom line, before you spend a lot of money changing parts, try changing
fuels.

Hope this helps,

Len

Damn this egg smell.

I get it, badly, pretty much all the time now.  I thought it might have been
a result of installing the MTM chip right after I got it, however it smelled
like this prior as well.  I'm obviously running rich then I'd say, and my
kitties are a toastin'.

I'm @ 90k now, lack of docs on the car makes me 'assume' the O2 sensor is
original.

Question:  do you recommend replacing the O2 as a 'most likely culprit', or
do any of you have other suggestions (aside from enjoy the daily egg
breakfast)?  If so, I believe I've seen some speak to a 'universal' Bosch O2
sensor rather than replacing it with the OE one, for more reasonable coin?
If so, who's the best to get it from?  Partsconnection.com, etc.?

I'd like to nip this soon before my cats no longer work.  If they DO go,
there's no way I'd be replacing them willingly, that's for sure.  I'd go
with some of them hollow ones.  Interestingly, I've heard a 50/50 split from
many that it WILL / will NOT pass CT emissions w/o the kitties.  The guy I
ran into last week with that Smart Car I told you about mentioned to me
briefly that his chipped '95 with 90k was running hollow cats, and he failed
1st time emissions by a C-hair.  Ran it with some 100+ octane, dry gas, and
a gillion MPH on the highway to the 2nd test, and squeaked by.  Thought that
was an interesting point of reference.

TIA!
