Civic EG

^^ I have no idea where to start . What can cause this?

the motor oil smells like gas also.

my d15b7 used to do this a few months after i purchased it when i got on the freeway it smelled like gas or fumes i was definitely running rich. I replaced the o2 sensor and the cat converter ( cat was burned in the inside honeycomb) and after never had that problem again.

Does the catalyst really make that much of a difference?

I'd rather delete it, than replace it.

Try a new o2 sensor first. They can be going bad, just not bad enough to throw a CEL yet.

thanks teal, im getting one asap

Just checked out this vender price is good, but this is a two wire and my car has a 4 wire o2 sensor?

I know the motor in my car has been replaced but don't know what year d15b7 has the 4 wire o2?

some detailed info would be awesome

I never heard of a civic having a 2-wire o2 sensor... that's kinda weird. Maybe their info is wrong on that part #

I think this is what you're looking for:
