Bank 2 system reading lean Just installed longtubes and ory on my car and I'm now getting that the bank 2 system is reading lean and the o2 heater is throwing a code. I deleted the air system before and when I got that tuned out I also got the rear o2's tuned out so I didn't think that was the cause of the engine light. Anybody know where to start with the bank 2 system running too lean?

How do you know that it is running lean. Are you using a wideband or got the DTC for it. Either way I'm sure it's just your sensor screwing up. Either the wiring for it or the sensor itself. Either way switch it out and problem should go away.

Had the exact same problem, put the car on our lift and swapped out the sensors and the problem moved to the other side, just bought a new sensor cleared the codes and it runs fine.

Before you buy new 02 sensors be sure you swap the bad one out with the good to be sure that's your problem, you don't want to go wasting money on something that you don't need.
