Perhaps it was written down wrong? P0134 is CKT no response and P0304 is misfire on cylinder 4.

The P0 codes are industry standard and they mean the same thing on all engines.

The P1 codes are manufacturer specific, and COULD mean different things on different engines.

 

ah i did type that incorrectly some how its is P0134 and P0135

 

Both of those codes are for bank 1 sensor 1.

Swap the front sensors side to side and see if the problem follows.

If it does follow the sensor, the sensor is bad. If it doesn't and the problem remains bank 1 sensor 1, it's probably wiring or the computer. If the problem goes away it was a connection issue.

 

okay ill let my exhaust cool off and swap them if that doesn't fix it whats the next step if its computer related?

 

If you didn't have these codes with the old sensors, it's probably not computer related. It could just be a new sensors that was DOA.

 

these codes where active on the original sensors which is why i replaced them if they are DOA they have a 1 year warranty so i will just have them replaced.

 

unplug the bank 1 sensor 1 o2 and turn the car to the on position and use a test light and see if you have power.

 

okay if i do have power replace the sensor if i don't have power check the fuse if fuse is fine then what is left?

 

If the fuse were the problem you would have more then just one sensor having issues, because I believe they are all tied to the #2 fuse under the hood.
If you find you don't have power at one plug then more than likely you have a short in the wire somewhere. The next step would be testing the correct power pins at the engine management ECM under the dash to see if you have power there. If you have power at the ECM but not the O2 plug then you have a problem in the harness somewhere between the ECM and the O2 plug.

 

Both front sensors are throwing the same code just different numbers i forgot to write down the other numbers for the second sensor. if its somewhere from ECM to O2 Plug am i basically screwed
