Agreed. Bad cat's small like rotton eggies. Might be time for a new cat...among others things to fix your rich mixture.klungemonger said:Probably the O2 sensor, and if it's been happening for a while, that smell might be a dirty converter from the rich mixture. They have been known to put off that eggy aroma.
He did that, I just want to know if he's driven or tested it since he installed it.KoolAsian said:New Cat my man!

i have a 94 civic dx with a super bad smell coming out the exhaust. a friend of mine told me the smell is like unburned fuel which i believe would explain my bad gas milage too.
i hooked up an air/fuel ration to it (at the o2 sensor) and the guage stays stuck on rich.
they car only recently started doing this.. i have also noticed that sometimes the check engine light goes on.. but when i turn off the car and turn it back off its gone, so i cant get an ecu reading.
what would cause this.. and what can i do to fix it.
is it the o2 sensor?
its a 94 civic dx, sohc non-vtec
