Rotten egg smell
Hello everybody
I have problem with my 00 jimmy when it run I smell rotten egg from the tail pipe even if you are far away from it. So, I think maybe the O2 sensor is bad which cause wrong air ratio mixture and this will result this smell. When I check under car there no O2 sensor nothing at all.
It is possible that the car run without O2 sensor?
thank you

Yes, GeorgeLG exactly no ports for O2 sensors in the exhaust pipes nothing just normal round pipe and no codes, no engine light .
I see the original gm Catalytic converter it's not same. It doesn't have out shell. It seem like mini exhaust muffler.

Here are the photos of the exhaust system
This what I mention before it seems that the Catalytic converter swapped by small exhaust muffler.

It looks like someone hacked out the O2 sensors and cats. Not a big deal if a speed density tune was properly done, but I'll bet a six pack that's not the case Your truck will just stay in open loop forever and run off the VE tables in the ECU. Is your CEL disabled too?
