Here's the dilemna...
My car fully warmed at idle produces 650 rpm while stopped.
Coasting on the highway gives 830 rpm or so.
If I am sitting still the idle is 650 but even starting to roll in neutral in will bump up to 1000-1100. Or if I am at lower speeds from 10-40 it stay at 1000-1100 from a while before coming down to the 825 idle.
The highway rpm drop is decent and acceptable but this weird in town hangin at 1100 rpm is unacceptable.
The reason is that at idle speed of 650 it shows .19 gph and at 825 it gives .21 gph. When it does this idle up crap I am showing .3 gph or 50% less fuel economy....
What can be done about this?
