My daughter turned into a gas station(small "bump" incline), and her Accord stalled out. I started it, but it was idling very rough, and would not stay in idle. I drove it home(less than a mile, keeping the rpm up at stop lights), and it seemed to have no loss of power. No dummy lights, but is throwing the trusty o2 sensor code. I have replaced the plugs, idle air control, and egr valve(control and valve were used, but very clean). Still won't stay idling, and running rough. Could it actually be the o2 sensor causing this? Any pointers or suggestions would be appreciated. Thanks!

 

what code is it throwing? Have you checked the codes since it started running poorly?

 

Only throwing an o2 sensor code

 

There are several codes for O2 sensors, so what is the code, like P1234.
