Car back from dealer. Nothing found again. Didn't have my hopes up this time. I wounder if the difference in the mileage is a difference in the timing of the cams to the crank. I wonder if maybe that is what is causing the difference. In the old day you use to be able to turn the distributor a little. Don't know who I would ask about adjusting it these days. Just a theory of mine.
