O2 Sensor replacement
About a month ago, I got a CEL to change the O2 sensors. I haven't noticed a performance or fuel efficiency drop. Should I change the proper sensors right away or can I let it go for a bit. Also, are their any issues with using a cheaper NGK sensor as opposed to the more expensive OEM part?

You can wait if the CEL lamp does not bother you, or if ou dont see a change in performance. Mind you the rear sensor does not feed into the ECM in a closed loop feedback for engine management. The rear sensor will never affect performance.
