Rotten egg smell??

2004 Accord 4 cyl. is emanating a rotten egg, sulpher smell from the
tailpipe. I thought this indicated a catalytic converter problem. But in a
new car could this mean anything else??

 

High sulfur gas. Try some different brands.

"Sulfur-containing compounds are naturally occurring components of
crude oil and, as a result, are also present in gasoline unless
removed. The national average for gasoline sulfur content is about 350
ppm, and as much as 25% of the U.S. gasoline pool has a sulfur level
of 500 ppm or higher "

I believe their is a TSB on this.

You may want to check around or just contact the dealer.

Is this just after a hard run or all the time?

As someone else suggested, try different gas.

So what does it say?

The site won't let us humble folk in.

 

Stop farting after eating rotten eggs!

It means BAD gas. Change to a different brand.

 

I had the same problem with my 2003 Accord 4 cyl. After repeated battles
with the dealer, and their successfully stalling for almost a year, the
smell went away. I had finally gotten them to agree to changing the
converter when it stopped stinking.

They did tell me to change brands of gas (to a specific brand), which I
responded no thanks. I was using a major name brand, not the cheapest in
town cash only variety, and figured if they couldn't design a car exhaust
system to work with any brand of gas, it was their problem, not mine. But
alas, it was I, not they, who tolerated the stink.

Oh well, now that the smell is gone, I do like my car. It took almost 20,000
miles for it the smell to go away.

Yes, stop sniffing your tailpipe.
