Hello,

Please correct if this is the wrong subforums for this,

Could anyone point me to resources for the emplacement and wiring of O2 sensors in a first gen B16A? I have one swapped into a EK civic, and I think the sensor must be acting up since the car burns rich and has bad mpg. I'm not sure what model ECU it has, I'll see if I can pull it out soon. I think it only has a single O2 sensor, as there's a disconnected O2 connector dangling in the bay but it doesn't throw a CEL.

Cheers,
