Did Catless DPs, now codes and limp mode.
WTF?! Back in my LS1 days life was so much simpler. I am totally lost on this platform. What did I do wrong this time? I put the pipes in. All sensors are back on. I am not getting O2 codes. It starts up fine. About 15sec in it throws the codes and starts running like crap. Missfire codes and 10895 and 10700. Niether of which I recognize. I am almost certain it is user error, but what did I mess up?
Thanks again.

You probably switched the O2 sensors. Black sleeve is for "front" turbo.

I thought gray was front. hmmm. OK. I will switch and see what happens. But I would think that the computer would not know and that it would not make this happen since in either possition it should read pretty close to the same. But I could be mistaken.

The DME uses the O2 sensors to reference and verify AFRs. One DP is bank one and the other is bank two, when it tries to adjust AFR in bank 1 and bank 2 changes instead the DME freaks the fuck out. Also, it uses the O2 sensors as a means of misfire/knock detection so that's probably why you're getting misfire codes.

It's all good. At least it was a simple fix!
