Today I was driving home from work and there was a stretch of highway where I hit about 110mph for a short distance; I quickly slowed down when I encountered a burning? smell, and other obvious reasons. This is not the first time I have encountered this burning scent however, it seems that whenever I reach speeds of 100mph and over I can count on this burning metallic sulfur like scent. I have a 2004 crossfire coupe, just purchased about two months ago...Any help would be greatly appreciated.

Thanks, Renzo

 

I get the same thing, it's from the cats.

 

ok so its all normal? nothing I should have a professional look at?

 

Sometimes I smell something too! A slight hint of something but I can't describe the smell. Only when I push the car beyond 100.

 

Cats just love a warm spot to sleep.

 

I usually do not smell the cats, but friends of mine say that they sure smell them when I pass them. Seems to only occur during wide open throttle. Seems to be common....

 

I haven't gotten that fast in my Crossfire, but if it could be the cat converters. When they run too rich for a while you'll get the sulfur smell. And I'm sure you had your foot to the floor boards to get up to speed. If it goes away after a short spell of routine driving you're okay. If it continues, something is giving your computer a signal to run full rich. Any vehicle I've had over a 100 didn't have cats on them. I love my Crossfire, but for raw guts I miss my '70 SS 396.
