560 SEC smells like rotten eggs!!

Hello there-

My 560 sec emits an odor like rotten eggs out the exhaust at idle. It's pretty pronounced. Too rich or too lean? Which way does one turn the mixture screw to lean or richen the mixture??

I replaced some injectors recently and the car runs way better but now has this smell. I suppose someone reset the mixture to compensate for dirty injectors but now I don't know which way to turn the screw to lean it out. Help!!

Alex

Sulfer in the gas. There is nothing wrong with the vehicle.

generally caused by high sulfur crude[venezuelan, for instance] that is not refined to a high degree.

i find that if you change your gasoline source to a better than discount one, this aspect of your combustion will disappear. stay away from citgo, sam's club, costco, and other big time discounters[such as kroger, heb, safeway].

you can smell the source of your fuel.

from shell, chevron, i bet you will never encounter that odor. but do the cheap stuff[lately i tried heb in houston - wheeeeew, does it stink] and you will be smelling sulfurous exhaust fumes.

my guess is that you won't be smelling this from pumps in california, since california is the only state to mandate virtually negligible sulfur levels. but for the rest of the country, the refining industry says, screw your olfactory lobes.

interestingly enough, it is the refining industry's refusal to reduce the sulfur content that is also preventing the operation of clean diesels. so, write your congressperson, tell them to mandate sulfur free fuels asap.

going further, this topic can venture into the realm of biodiesel - one of the best answers for hydrocarbon indenpendence. imagine, not ethanol blended with crude oil, but canola oil, grown entirely in the usa, fueling your common rail diesel.

just a thought.

Sounds like an old/sick or sooted up catalytic converter. If your car runs well you probably need a new cat. This is one of those instances were a NOS part is not a good idea. The cats of today are much superior than they were originally.

Very good, and biofuel made from hemp seed oil is even better, yelding more product per acre than canola. See www.canadianhemp.com, I think thats it, Manitoba and Suscatchuawan(sp?) have started growing commercial hemp. Do a search, support industrial hemp.
