i have a 93 accord with a complete jdm 95 h22 swap with ecu. i used a universal O2 sensor and it seems to be ok. after a couple of months, when i get on the car hard, the check engin light comes on. i check the code and it throws 1, which is the o2 sensor code. i checked all the wires and connections to the o2 sensor and they are all fine. when i reset the ecu it shows no coeds, but when i race, it comes on after a bit. is it because the o2 sensor is universal and not honda???? any ideas or suggestions???? please help, this problem is really killin me.

 

Is this 0² sensor 1, 2 or 4 wire? The codes should tell you what is wrong if it's a 2 or 4 wire sensor.
