Hey guys I have a 2002 Honda Accord with the f23a1 engine in it, and Its been throwing a po172 code for the last 4 months. During those four months I replaced the fuel pump twice. I replaced the fuel injectors. Spark plugs, plug wires, catalytic converter, upstream and downstream O2 sensor, pvc valve, and maf sensor. All to no avail. Finally last week I decided to replace the fuel injectors with remanufactured ones which seemed to fix it, but now it's throwing a po171 too lean code. Any advice would be greatly appreciated.
​

 

Could this be a computer issue?

Since you replaced the catalytic converter, could there be an issue with the O2 sensor?

I ask because some pill head STOLE my catalytic converter and the shop told me "straight piping" my car would result in the computer going too rich or too lean with the mixture since the sensors would not be reading anything there.

*And since you replaced your catalytic converter, could you go to my thread on "catalytic converter theft" and give me some advice on how to replace that?

Thanks and good luck.
