. I'd look for an exhaust leak on that side. Did this just start all of a sudden? 
LTFT way off one bank
LTFT way off one bank My LTFT is wayyyy off on one bank with no throttle, car feels wayyyyyyy down on power. I've attached my log. I'd rather get a quick opinion befire I start swapping parts out.
I'd definitely check 3 things first: Exhaust Leak, O2 sensor, or injectors.
From the looks of the log, It looks like your Bank 2 injector may be on it's last legs. Swap O2's from side to side and see if the problem follows the O2 sensor.

seems like you have a bad injector, we ran into something like this when we installed some new 37# injectors, and didnt look at the part numbers, come to find out, that only 3 of them were 37# injectors. .... but if you have one go bad on you, then it would do about the same thing.. .. My 2 cents
My car seems to have same problem and didn't have it a few weeks back. My passenger side is reading high. Seems to go closer to same though when giving it throttle.
So not sure best way to figure out which cylinder is doing it. Wonder if power balance test will show the problem cylinder. Only problem is power balance dont work with beta 2.23 build so have to put 2.2 in again to check the power balance.
Will be watching this thread or please pm me if you figure it out. I have new 02s to install denso hear they are same as gm now and way less money. Had some problems with plug wires but think they are fine now.

pulls the plugs last night, 1,3,7 are black as hell, computer is adding fuel but doesn't need to. #5 looks like it had oil on it, I was a little concerned.
will post pics tonight
Any new advice?

Ok so I might have figured this out.
pulled plugs a few days ago, 2,4,6,8 looked fine, 1,3,7 were black as hell and #5 looked like it had a little oil on it. I kow my car pulls oil through the intake so it made sense that there might be some oil on it if it was getting no fuel.
Fast forward to today, hooked my wideband up, which happens to read from the drivers side bank. and at idle it pegged out and read len for lean. so I knew something was bad. while it was idling I went to the engine bay, unplugged #1 injector, not much happened, plugged it back in and got a little surge in the idle, repaeted for #3 with the same result. Got to #5 unplugged, nothing, plugged back in nothing....So I come to the conclusion that #5 was getting no fuel. Then it clicked in my head..... when I bought the car it had a remote start system. THe system tied wires to each injector. Last year I ripped all that **** out. so i went through the harness to check the connections, low and behold the #5 wire was completely disconnected. So i'm heading out to solder it back together and see if it fixes the isssue.
