"Okay, I have an LS-VTEC in my 91 Integra. Its chipped and runs sweet. When I shift at 8000rpm, flames come out of the exhaust. Now I know the 02 sensor is bad, could this be because of that? By the way, I'm running 91 octane."
It cant be running that sweet if the O2 sensor is bad.
Replace the sensor if you know its bad. Will it cure the flames? Maybe, maybe not.
