Uh...do you know for a fact it's running rich, or does it just smell rich to you (and the others commenting) because the cat is gone? Huge difference in exhaust smell with no cat.

Hmm, good call, seems logical to me. Guess Ill live with it cause a cat aint going back on. I don't want to screw with it now cause its running the best it has EVER since Ive had it

Part of his point is that lean stinks too, so exhaust smell doesn't automatically mean it's rich.
