Thanks for the reply. It was 20.7 steady after driving the car up to temp and going home and checking while it idled. The following morning I drove to work 35 miles, pulle dinto the lot and popped the hood and check and it was 30.6 and steady. My fuel consumption is about 20mpg so it's not poor by any means.
As usual, I am left with no answers. It's a situation I have become used to. At least now I have a $30 piece of equipment to confirm that I have no answers.
