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.

 

well, the o2 sensor is heated or not? im having the same problem, but its different in its own self, just get a new bosch 02 sensor....
