I replaced the firewall side o2 sensor and it lasted one day and poped code P1133. Is it possible that the front sensor is bad and how do I test the new rear one?
Do you
have the same problem?

Yes, could be a downstream O2 sensor. To learn how to check an oxygen sensor, follow the link below.

If all O2 sensors are OK, need to have catalytic converter flow tested.

By front I mean the radiator side of the engine (front wheel drive) could that one be bad also?
The firewall side fuel air sensor is called bank 1 senser1. On the code reader should it say bank 2 sensor 2?
Should I use OEM? The parts store gave me a Delco, could it have conflicts?

You say code P1133. You mean code P0133 or is it California emissions vehicle?

Code P1133 indicates a Air/Fuel Sensor (AFS) circuit response malfunction.
The AFS is located in each exhaust manifold. You can use an ohmmeter to measure resistance between Black wire and Black/Red wire (bank No. 1) or between Black wire and Black/White wire (bank No.2) at the AFS connector. Resistance should be.8 - 1.4 ohms at 68F (20C).

If the code is P0133 then the bank No.1, sensor No.1 needs replaced. This sensor is the one located on the side of engine that includes cylinder 1. The sensor No.1 refers to the sensor closest to the engine block.

I always suggest using OEM parts on vehicles. They last longer and perform better than any other brands. Of course, they do cost more so you will have to judge which one you want.
