I have been driving around for a couple of weeks now, staring at the CEL. For S's&G's I decided to get my codes read at autozone. 2 came back. 0135 & 0155, both saying "O2 Sensor Heater Circuit". So, for all you code gurus out there, what is that telling me? Currently the rear 2 are connected and the front 2 are not.

I know, I saw that. I'm just gonna splice & solder my wires when I get the chance. So, do those codes mean anything to you? I'm assuming they are referring to the 2 rear sensors seeing as how the fronts aren't connected. But, I do find it funny that I'm not getting a code about that.......... hmmmmm.

its b/c they arent hooked up.

Im not certain but im sure P0135 is for bank 1 sensor 1 and P0155 is Bank 2 sensor 1

Yes, it's a fault for both primary O2 sensors.
The car will run much better once you reconnect the sensors or have it taken care of with an SCT tune file.
