I replaced the o2 sensor on the header with a new one and i am still throwing code #1 I have a 95 eg with a B16 fully built head and stock block running a DC sport header with an apexi full exhaust any comments would be appreciated

 

HElp Please

 

ECU? What wire number of o2 sensor?

 

I think that some of the wires going into the ecu are messed up i just checked it out that could probably be the problem

 

Sounds good. I was just wondering, cuz if you had the ecu and sensor mismatched it'd be no good.

 

im gonna try to fix it tomo i got plenty of wires to repin it
