I'll have to see if I still have pictures of how the O2 sensors are plugged in

It's hard because they are both the same length. I pulled them from the clips so I could make them reach. But I'm not throwing a code on rear sensors installed wrong.

My primary's weren't mixed up, my secondary's were.

However i swapped my primary's while troubleshooting and it idled like crap when i switch them. It was constantly misfiring.

Mixed up secondary's(Post catalyst) o2 sensors will run seemingly fine, but it's doing the same thing as mixed up primary o2(pre cat) sensors to a slightly lesser degree.

The o2 sensors with the BLACK heat sheath, are for bank 1


The o2 sensors with the GREY heat sheat are for bank 2
