View Full Version : sulfer smell

Got entire exhaust system replaced last week... (I passed emissions test). Now I'm getting this nasty sulfer smell (stinks like a sewer) out the exhaust. What's causing this?

That's the smell of the cat. "over-working", it usually makes this smell when you are running rich (i.e. going up a small steep hill at low speed)

Replacing your oxygen sensor may fix this problem. They most commonly make the vehicle run rich when defective. Had this same problem on my 94, so I replaced the sensor and installed a hi-flow cat. The smell hasn't been back since.

The O2 sensor was replaced... (they also said they needed to reset some codes or something). Sometimes I can smell it when I'm at a light.
