Lean code
I installed my longtubes a few months ago with resonators. I installed the front O2 sensors, but my rears where both pretty much welded into place so I left them off. I have a tune from PHP to account for my cat delete, but just about a month ago I started to get a code for my bank 2 running lean. I was towing something at the time on my tow tune, so I switched back to the performance tune and cleared the code, but a few days later the code popped up again. Is the fact that I do not have my rear O2s causing this or is it something tune related?
