Thanks for the bump. A new MAP sensor has improved the gas mileage in a way. I am now getting between 10.5 and 13, regardless of kind of driving I do. But the mileage is highly variable even when the driving is the same. I used to average 14 mpg.

But, the hesitation/stutter problem is back, but only on start-up, not while driving. I am wondering if it has something to do with summertime gas mixture of something to do with pressure.
