I have ~ 1000 miles on my Cobra now, and because of some posts on this board, I'm a little worried about my cats clogging. My car is a second run vehicle with nothing more than a Densecharger... I've noticed a funny smell after I drive the car...sort of like a skunky burning smell. Should I worry? Is the cat clogging problem a result of Ford's excessive fuel at the top of the rpm range?
