I decided to calm down and wait to see if the PCM learned. I drive maybe 200 miles a month so its slow. Anyway this thing seems to have learned whatever it needed to or it likes the cold. The only issue now is that it likes to shift super fast as I take off. God its nice to feel the thing move right away when I press on the gas for a change. It is jumping from 1st to 2nd before it gets past 10mph. The idle is staying high and it has this thing where it downshifts and jumps just as I come to a stop. This causes me to have to press extra hard as I stop at the end.
So I'm thinking maybe a few more tanks of gas to see if it learns more. Oh yea found this http://pure-gas.org/ and just added a half tank ethanol free gas which seems to make it even happier. Its nearly a dollar more per gallon.

Your transmission is controlled hydualicly except for overdrive and your lock-up torque converter. You might have sticking valves in the valve body since you don't drive it that often.

The alcohol in gasohol, E10, or whatever you want to call typical pump gas, might be absorbing water out of the air because it's cold and could be causing your running condition because you don't drive it enough. That's why it runs better with straight gasoline. Straight gasoline is going to be more expensive because ethanol is subsidized by the federal government making it cheaper.
