Rotten egg smell

My 2008 Powerstroke seems to run great but recently I have noticed a distinct rotten egg smell in the exhaust. This seems to be a change since I never noticed it before or at least not as obvious. There doesn't seem to be any other indication of problems that I can see. I don't have a code reader but no error messages or check engine lights and no difference in how the engine sounds or runs. My concern is that this change in smell might indicate a problem with fuel mixture or something. Does this sound familiar to anyone?

Thanks.

Pete

Sometimes my buddies 08 smells like that to. Heck I haven't even smelt a "diesel" smell out of none of these new stock trucks. Dunno what it is. I just kinda figured it was the ulsd in that new motor. Dunno though.

I have another friend with a duracrap and it always smell sulfury

My 99 smells like diesel, wonderful, rich diesel

Mine has a different smell (other than diesel). I thought it was something in the ULSD. Maybe one of the things that makes it foam so much.

I have the cat on since mine is stock, but mine doesn't smell like rotten eggs. Just not the normal diesel smell

Thanks guys. Yeah everything is stock. Cat is still on. Maybe I need to talk to my tech about the cat. Sounds plausible.
