Isn't it catalytic converters that smell like sulfur when they die?
i mentioned this a little while back, and i went to a mechanic and he told me to just try better gas. when i tried, there was a significant difference in the smell i was getting form high revs, but just recently after maybe the third fill up on premium, i'm getting the smell again.
the smell is jsut like sulfur, this mornign i smelled it from my vents and then i opened the window and it was the same crap smell i would smell from my exhaust. the smell from the vents was noticably more, for lack of better words, stinky
any ideas what this is?
