So I just finished my engine swap, I have LT's and ORY. I only have the front two sensors. I have had the p0134 code and ill clear it and it keeps coming back. I have checked voltage to the connectors, installed new 02's and still nothing. Is this a code that I can just have changed to "no error reported" with hptuners? Or does this need to be fixed? I don't want it to hurt anything but I am pretty sure that these are for bank 1 sensor 1. Any input is appreciated.

It needs to be fixed. Period.

Possibly caused by the long tubes not allowing the o2's to heat up completely. Could also be incorrect o2's being used for your particular harness, or incorrect wiring.

Here's a thread to help you out:

thanks, yeah I was not sure if it was part of not having the back o2's. I have heard of some people deleting it, and I had to at least get a legit answer.

i am running with no o2's, no issues at all and mine were deleted.

So, you're running OLSD? I think you might be confused here, as the OP is not talking about simply deleting rear o2's (which just measure catalytic converter efficiency)....he's talking about the FRONT o2's....largely responsible for proper closed loop fueling. To not have them (OLSD), would mean that you're rarely running ideal AFR's from day to day.

that's exactly why, I found out my issue... my front o2, driver side, was plugged into one of the rear o2 harnesses. I realized that when we did the swap I ripped a plug as the engine was coming out, and simply furgot to connect it back up and my buddy accidentally plugged it into the rear one.
