I was unaware that they ever made a 97 si.

Black smoke usually means too much fuel. CEL? or just flooring it with a fart can?

do you realize that you're in the 4th gen forum ... and you're asking about a 6th gen civic?

Hows your gas mileage?
How old is your o2 sensor? Are you running a stock ecu?
Are you sure the smoke isn't dark bluish? If so, run a compression test: dry and wet.
Like turtle said, I also have never heard of a 97 civic si. Whats in it a B16?

i'd put money that there isn't a 97 si in the states. what's done to the engine?

yeah 97 si im from canada, o2 censor is newish and stock ecu.

black smoke is rich
blue is oil
white is head gasket

never heard of a 97 si, sounds like someone jus put a si badge on it or u got the wrong year...

are you people not reading???? lol. he just said hes from canada. The Si up there is the EX here in the states. the SiR up there is the Si down here. do youre research before flaming on the guy...
