I have a 99 civic 4door that has been boosted for about 2 1/2 years. Its been tuned on the newest set up for a couple months. and the last 2 days it has been running rich as fuck. It usually cruised at 14.8-15.0 Now its running at 12.5 at all times and then goes all the way to 10.0 then sputters.  Is it the o2 that has gone bad, bad injectors?

bad wideband?

[jagojon3]

If it runs the same I would doubt the injectors are the issue. Check O2 sensor first, then wideband controller like bone said.

edit-oops just saw you said it sputters. Clogged cat?

[clwtwizted]

No cat. Ill try replacing the o2. I have a spare set of dsms ill swap out if that doesnt work. This shit is killing my gas  milage. Sorry. I meant to post this in the engine management section. My bad yalls

Jumped timing will do that, too.  Check your cam gearz if you've got them.
