Fuel Injectors bad but no misfire?

Is it possible that your fuel injectors can go bad without having misfires?

I kept receiving lambda codes pre cat and post cat:

2C32
2C2C
29E1
2C7C
2C6A

I replaced my front 02 sensors...cleared codes. After a week the codes came back. I'm not having any issues with misfiring and the car seems to be fine WOT.

What could it be? Did the front O2 sensors fail again after a week? I'm not running a DP fix btw.

Yes, it is possible.
My car ran rough and didn't throw any codes for a while. YMMV
The eventually started throwing codes.
