P0135, P0155? Why?
i just did a full exhaust on my 02 z28 and it has been throwing o2 sensor codes ever since... the codes are from bank 1 sensor 1 and Bank 2 sensor 1... If you know why it would be throwing these codes please post up.

If you had someone else put on your LT's, they probably messed something up. Its odd that the sensors would just go bad on both sides after someone had to reinstall them.

These are heater malfunction codes and they most likely need to be replaced.
Oh and fwiw mine went bad almost right after my lt install.
OP just swap the o2s and run the car. See if the codes come back

New O2s all come with anti-size on them from the factory. Since it burns off after the install, you need to re-apply when re-installing to be sure to prevent the threads from fusing.
I had a dealer pop one out and not use anti-size compound and the thing fused. Recovering from that was a hell worse than I can describe...
