Help !! - 2004 Accord - Bad Odor

I have a 2004 Accord LX with about 1,400 miles. At times it gives off a
powerful odor like rotten eggs or sulfur. I've seen posting on several sites
where they say that the company is claiming that this is not a problem. Has
anyone else experienced this and had it taken care of by Honda?

I'm taking it in for the airbag recall in a week and plan on having them look
at & handle this problem but have heard that the dealers are dancing around it.
What have you experienced?

This problem occurs because of sulphur in the gasoline.

Eventually the catalytic converter will get coated to the point where the
smell goes away, so this problem is self-limiting.

I cannot tell where you're from, but your jurisdiction has relatively lax
regulations on sulphur in fuel. Are you in Canada?

Try a different brand of gas. This may get rid of the smell as another
brand may use base stocks that contain less sulphur.

I'm surprised the dealer hasn't told you this.

 

This problem is caused by gasoline with a high sulfer content. If
you're sure it's coming from your car, change your brand of gas.

" Most gasoline sold in the United States has fairly high sulfur
levels. The national average is 350 parts per million (ppm); as much
as one-fourth of gasoline has a sulfur level of 500 ppm or higher,
according to petroleum industry figures. On the other hand,
California, the nation's smoggiest state, now has a statewide sulfur
standard of 30-40 ppm. California's standard allows refiners to
produce gasoline in batches that meet a sulfur content average of 30
ppm, so that in some cases, sulfur levels in gasoline can be as high
as the state's sulfur cap of 80 ppm. Most northeastern states, also
suffering from high ozone levels, sell reformulated gasoline with
sulfur levels of 150 ppm"

Are you sure it's not coming from the car ahead of you? Try putting
your ventilation on recirc and see if it goes away.

TeGGer: maybe this should be in the FAQ?

 

Good idea. Will add it.

 

Some folks noses are more sensitive than others.

 

The rotten egg smell is caused by the same thing that makes rotten eggs
smell like rotten eggs: Sulphur. Only in this case the sulphur is in your
fuel.

Eventually the cat will get coated to the point that the smell goes away.
Until then you can try different grades and brands of gas in the dim hope
of finding one that has less sulphur.

All it means is that your cat is working very, very well, and is attempting
to catalyze the sulphur in your gas into sulphur dioxide.

This will be added to the FAQ soon...

ALL new cars are plagued with rattles, buzzes and squeaks from the
interior.

Since automakers have to reallocate their monetary expenditures in order to
satisfy regulatory and consumer demands for "safety" and emissions, the
money has to come from somewhere. The interior is one convenient place,
especially since it is not structural, is subject to few regulations and is
sheltered from the weather.

With Honda's stated aim of turning their cars into rolling rubber rooms,
expect ever cheaper, flimsier and rattlier cars. I'm hanging on to my '91
as long as I can.

Depends on where you live, the mileage on the car, and how perceptive you
are.

It will go away. Just wait. This has been going on since monolithic cats
became common in the '80s.
