Stinky Bravada?

[bigred36]

I own a 94 Bravada(115K mi) that stinks like crap out the exhaust. I have replaced the exhaust from the catalytic on back and put in a new egr valve plus a O2 sensor. Different grades of gas don't make a whole lot of difference either. The muffler shop said the catalytic conv. was
okay and it wouldn't make it stink if it was bad. No coolant loss just a real bad smell all the time. It is smelling a little rich at times. Any suggestions would be great before I give up and take it in.

I have a 94 Bravada (112k mi), so far so good. No smell. When did you problems start?
