Seems I have heard Click and Clack on NPR talk about some other problems that can happen when good thermostats go bad. One of them is poor gas mileage. If the temps never get to the right place, other inputs to the CPU don't happen, either.

So, any issues with your fuel mileage?

Did the new thermostat help it?

We're all curious, so clue us in.
