Default Problem solved

I contacted KidFuzion and he told me that he solved the problem by buying a new O2 sensor from Honda. I did the same and it solved the problem also. Just wanted to update this thread with the new info.
P1167 and P1166 codes relate to the primary O2 sensor heater malfunction.
I tried two different O2 sensors, a "universal" sensor from Autozone and a supposedly OEM sensor from O'Reilly's. Both of them caused the car to throw a P1167 code and run rough. I finally purchased a O2 sensor from Honda, and it fixed the problem. It turns out that none of the aftermarket probes from Bosch or Denso will work on a ULEV (F23A4) 4 cyl. engine. Honda had different part number probes for the normal VTEC 4 cyl. and the ULEV Vtec engine and the probes look different and have different length cables. The computers at O'Reilly's, Autozone, or NAPA made no distinction between these two engine types.
