o2 sensor codes I got p0131, then the next day:
p1131 (which doesn't have much info on it) and p0138, do I need to replace both front and rear o2 sensors?

The codes are saying there's a problem with both the precat and postcat driver side sensors. I'd replace the precat sensor first, delete all codes, then see if you get P0138 again.
