If an 02 sensor is bad would it affect the power at all? I know on Ram's people say they run like dogs and I know the Accords run fine but just wondering do they effect power if they are bad?

 

well if any O2 sensor is bad, your car is going to run rich.. im sure that it wont hurt your car... but it is something that i would want to fix

 

On an OBD-2 car the 2nd O2 sensor simply measures whether the catalyst is working. If that goes bad it won't affect how it runs. The first O2 sensor will affect mixture control, probably make it run rich. Some engines run OK rich, some run crappy.

 

It's the rear 02 sensor that is bad.
