Well I looked through all your data, and bank 2 LTFT is a little bit high, but anything under 10% shouldn't cause any issues like this. I'm curious, when the car is running can you visually inspect your accessory drive? I'm wondering if you've got a dragging accessory or pulley that the car is trying to compensate for. That idle value is about right for when the A/C compressor is engaged, although looking at the data the car isn't asking it to be. I'm not sure what the engine load should be (I don't have the ability to compare on my car), but 15% seems high for just idling.
