Can't really help you without knowing the code. The obvious choice is rear O2 sensor failure but you need to be sure.

how do i pull code

 

[tonytaylor85]

take it to the parts store. They will usually pull codes for free hoping that you will buy the parts to fix it from them. Or find someone with a tuner.

Autozone always does it for free.

i use to have an o/r x and turned the rear o2s off with a turner and still got a code about one bank being lean, turned out had an exhaust leak. make sure you're pipe isn't leaking

thats why we need the codes!
