3.0 Poor Mileage

Hey all, recently I noticed that the OBC is reporting around 13MPG combined. I was shocked when I saw this because I thought I normally got somewhere in the 18-19 range. First thing I did was check tire pressure, They were all fine. Then I fired up INPA and looked at my adaption values. Everything looks fine. What about that "tv probe heating before kat bank 1" and 2. They are locked at 99.31. That means they are trying to richen the mixture, right? Let me know what you guys think.
