:puke CAR SMELLS LIKE BUTT

[another_nissan_owner]

Anyone know why the exhaust has a smell of sulpher to it. You know like rotten eggs to it. I just got the car and I am trying to finish somethings to it. I tell you it really stinks.

this is not entirly true. I have a gutted cat and when my air regulator went out the car had that same smell. It was also idling around 5k, and even after i fixed the problem it stil smelled like that for a while. It smells like that (someone corect me if i am wrong) because either the fuel/air mixture is too lean or there is a lot of fuel not getting burned. check for vacuum leaks

Could be running very rich too... check your ecu for trouble codes...
