Replacing front O2 Sensors
Hello, I have code P219A which is the fuel trim imbalance on one bank. It only occurs after a long drive at low and steady speed. It could be an O2 sensor that is just tired enough to read incorrectly but not enough to set off bad O2 code.
I think I just might replace the front O2 sensors since it won't cost too much and I hope I can do it myself. I have a 2013 LS3 and have an O2 senor socket, universal joint drive, long drive extension, and a long breaker bar. I think I just remove injector covers, disconnect O2 wiring and use the tools to remove sensor. Is it that easy? The car is new enough that hopefully it doesn't take too much torque to remove it.
Am I missing anything?

I replaced mine a few months ago and I ended up with one of the new sensors being defective. I chased wiring but could not find anything wrong and it was not until I swapped them side to side that I found the bad sensor. On my car the passenger side was the hardest to replace.

Ditto, start with data logging the sensor to see if one is lazy, swap the 02 to the other sides, data log again, and see if the problem chases the 02 sensor position with it now mounted on the the other bank side to start with.

That is the right way to do it but since the factory O2 sensors are about $58 each on gmpartshouse.com (or gmpartsdirect.com) I think I'll just throw some parts at it and see what happens. I use the car for open track days which gets the O2 sensors very hot and I think shortens their lifetime.
