running rich o2 sensor?

so im getting code 25 and 26. both are very vauge codes and have been running through the troubleshooting all day and the only strange thing i have found so far is my o2 sensor is about 2 ohms above the specified resistence so could it be bad even though its too high? other things i checked were cold start sensor, and maf sensor

hmm, only thing i can say if its not on the specifict resistance that it could be shot. check your timing, also you can adjust you maf is you try to two things above and still nothing

how about you post that list of other stuff?
...but before you do, clear the ECU codes and go drive a few days.

Codes were clear when it threw 25 26. Checked the resistance of the o2 it was about 2 ohms over. Replaced the o2 and no more code.
