My exhaust is smelling strong or rich. I don't know if it's just burnt dirt from mud getting on pipes or if my rigs really runnin rich? 98 xj sport, gotta cracked collector and the cat I guess broken inside which makes my exhaust sound like it's loose/beefier. and when I step out of the xj I can smell it...this happen to anyone else?

 

**BUMP**?

 

Mine does the exact same thing, it runs very rich and you can smell the exhaust. I'm probably going to change my O2 sensors.
