On a final note...I swear my gas mileage today was better than normal as I usually can't get more than 40-50 and rarely 60 miles on the first quarter tank...today I've got 45 and its showing 1/8 tank consumed.
That sounds about right. My mileage is starting to come up too, as the cold weather subsides...almost identical to yours.
I'm gonna re-set the ECU before I head out Moab way, to see if I can pick up a few mpg.
