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
