Rotten egg smell

I have been noticing a rotten egg smell when I take a short trip. I run up to the 7-11 daily, about one mile, and I notice the smell then. Any ideas what this may be? I have a '14 2dr 6spd.

Sounds like typical new catalytic converter smell.




Unless your 7-11 is built next to the sewer plant....

Hmmm ok. Should I take it in for warranty work or wait a while?

If you're going to be at the dealer's anyway, you might want them to confirm that it's just the new cats. But, I don't think I'd get very excited, or go out of my way unless it persists. It could mean that you have a fuel mixture or valve timing issue or something, but likely just the cats.

I'm sure others here will have better advice than mine, though.....

Probably the cats. Btw, what happened to your XR4Ti? I had a 1987 XR4Ti in high school, loved that car. One of the few performance cars Ford got right in the 80's.

I sold it a few years back, I believe it was gutted and a v8 conversion put in. They were certainly fun cars. My grandaddy had one and we had some fun in it.

I agree that it could be the cats like Up Hill said. Sometimes the brand of fuel can contribute to the problem, or with a winter blend. Did you recently fill up with no name gas someplace? If you did, run it down and try another fuel. Unless the dealer gets a code I don't think they can do anything at this point.

Rotten egg smell is classic cat. convertor break in. Make sure you buy from a good gas station and let your Jeep warm up really good in this cold temps we've had. Cats. need to be hot to work, and if you don't let them get hot enough they'll smell like rotten eggs. Take your Jeep on a run down the highway and let it get to running temp. {half way up Temp gauge} and do it once a week until temps start coming up. I do the same as you driving to 7/11 every morning, but I leave Jeep running and just watch from the store. Of course, I live in a small town in north. Mich. so that ain't a problem. But the fact is, you need to get your Jeep up to operating temps. and hold it there for at least 1/2 hour or so. That will also help oil life and help recharge your battery. You bought a Jeep, so drive it!!

Relevant to pass time:
Quote:
Unwanted reactions can occur in the three-way catalyst, such as the formation of odoriferous hydrogen sulfide and ammonia. Formation of each can be limited by modifications to the washcoat and precious metals used. It is difficult to eliminate these byproducts entirely. Sulfur-free or low-sulfur fuels eliminate or reduce hydrogen sulfide.
Quote:
Hydrogen sulfide is a colorless gas with the characteristic foul odor of rotten eggs; it is heavier than air, very poisonous, corrosive, flammable and explosive.

I agree. Cats can smell like rotten eggs when new AND when they are failing. Hopefully it's not failing.

I had a car one time smell like rotten eggs. I let it go for a while until it got worse one day. I assumed it was the cat also, until I opened the hood and found the battery smoking.
