Based on this and the photo of the plugs it looks as if you are running a tad rich on bank 2, i.e. passanger side.Just wanted to say thank you to the guys who took their time and looked at my plugs and gave me their opinion instead of giving me links to look at, I really do appreciate it. I needed some different opinions from people that are a lot smarter than I am. Thanks again. Here is a few screen shots from my scanner. This was at idle.

Could be a week O2 sensor particularly if you are up over 100K on the odometer. It could also be a small leak in the intake for that bank. If its a leak the O2 stft should level out with RPM to (or close to) bank 1. You want to bring the RPMs up to around 2k to check.
But overall those plugs look good, even for only 3K being on them.
FYI, colder weather will also ding your fuel mileage. Longer to get to close loop on the engine and longer to warm tranny fluid to optimum level for peak effeceincy. Its one of the reasons we have a fluid bypass on the trany lines to the radiator.
