Hi I just replaced all o2 sensors I have long tube headers and high flow cats, I have a mini cat extension for the rear o2s no codes for the rear, the front ones different story, keep getting P113D, P0153, and P0133, all of the sensors are NTK, any one know what could be causing this?

They are plugged as far as I can get them you think it may have to do with the extension harness?

I would use factory ones. The ones in the rear I have turned off by tuner. What type harness extensions?

The extension are jba, my rears ones don't show any codes I have mini cats on them, isn't NTK factory? My tuners been messing with the delay of the front o2s still a work in progress only codes I'm getting now is P0133 and P0153
