    The first thing I'd try is changing out the o2 sensor with an OEM one. Not one from autozone or an autostore. If the code is still there after a reset try changing the fuel filter.

    hmm that im not really sure..i guess you can pull one off a honda and cross your fingers its an oem one..most likely it is, but if the car has been sitting or is very old the sensor might be bad too..although i never recommend it, some people have good reviews on the autostore ones
