i have reason to believe that one of my o2 sensors is bad. i have an extra one laying around, but its from the other port. if i change it to the right connector, will it perform the same? i know if you hook the two up backwards it will run like crap, but thats not exactly what i'm asking. assuming they are hooked up correctly, are they interchangable?

thankyou

 

Yes they are interchangeable provided that they are both the same time.
