P0134 code probems now..
Little update, i had the front 2 o2s crossed so that resolved the running crappy problem but now I get the code :
P0134 Heated Oxygen Sensor (HO25) Circuit Insufficient Activity Bank 1 Sensor 1-
I tried to reset the ecm and drove again and it came back so this is the only code i need to resolve. anyone know what this means/ Is the o2 not working at all or not up to par?
Thanks
Dave

I drove it again, but also got these codes now :
P1133 Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1-8
P1153 Heated Oxygen Sensor (HO2S) Insufficient Switching Bank2 Sensor 1-B
As soon as the CE light flashed and went on steady it ran perfect.
?? wierd ??

The 1133 and 1153 codes are generally caused by the O2 sensor not getting hot enough, being too far away for the primary tubes. compare distance on stock manifolds to the headers you are using. I have the same problem. Some say this problem can be edited out in the PCM but I don't know for sure.
On scan the O2's function normally and my dealer said not to worry! I don't see any difference in power when the codes appear, just a pita.
