There is nothing wrong with your car...the smell is from the catalytic converter, yes...but its perfectly normal. All cars made in the last 10 or so years have this smell...often the newer the car the worse the smell. You'll notice it alot more when you're working the car a bit harder and generating a) more exhaust and b) more heat.
Just ignore it...its harmless.

Mine just started having this smell in the last week or two. I had a 99 Jeep before and it never had a smell like this. I don't drive the car hard. I bought it in March of 03 and it had 9100 miles and now has 15,000. Oh well, I notice every little thing about this car because I don't really like it. I think because its Gold I just have not been happy with it and it just seems like there is always something happening with it.
This is funny you mentioned this. When I first got my car 7 months ago it would smell really bad. Then I had the hesitation TSB done and a new air flow sensor put in and he smell stopped. And just yesterday it started smelling again. It has to do with the colder weather and the gas. Its perfectly normal. Oh btw I just hit 5000 miles tonight.
I just got my car back from the dealer after having the catalyst recall done. They did the fuel pump screen several weeks ago.
I saw the parts liist that they replaced and it seem to be everything from the exhaust port to the catalyst including the precatalyst . Anyway I was getting the sulfur smell that you were describing before the recall work was done and it is done now and no smell now. When it was in this time they also said that there was a recall on a oil seal that they took care of.
Does anyone know why there was a recall on the catalyst?
THe cats seem to be too close to the motor or something and have burned up on more than one occassion, the insides of the cat turn to fine sand and get sucked back up in under certain conditions...end result: scored cylinder walls and burning oil.
Haven't heard anything about an oil seal...can you post more info? Should be something about it on your work order slip.
There was nothing on the work slip when I called for a explanation he said that it was one of the items that called for replacment on the catalytic converter recall. I have a feeling that it was a Oil Seal that was in close proximity to the Catalyst. Anyway they did a oil change and a new filter (unfortunately they didn't know that I converted to synthetic so they had to flush the engine and put another 5 qts Synthetic.
Just thinking about what you said about high heat from the catalyst I have had to replace three O2 sensors out of pocket I bet that is what blew them.
The mini/pre-catalytics are on the exhaust manifold behind the engine, and they are a source of trouble for both the 2.5 and 3.5 engine. The 2.5 has one, the 3.5 has two pre-cats.
Generally a rotten egg smell is a symptom of high sulfur gasoline, or catalytics that are ready to die. This is not necessarily a normal symptom of a properly running car. My car has had the catalytics replaced (because they blew) and it has never smelled like rotten eggs, and here in Canada we have very high sulfur gas. Try Sunoco gas and see if that helps. They are a lower sulfur gas than any one else out there.

I'm amazed at how many poeple don't have rotten egg smell coming from their cars. Maybe its that wonderful "reformulated" gas we get in Western MA or something...all of my cars have done this in the last 8-10 years...new or used...the newer it is, the smellier it gets, but only after working it hard.
