Today, just driving around town, I was trying to make the FCD run as high as possible.
I used different methods and drove in different environments, with and without cruise control and this is what I experienced:
My HCH will not maintain over 40 MPG <period> unless I'm going down hill (at which point it goes all the way to the right immediately to "120") and my foot is off the pedal or in Cruise Control it seems to do the same thing.
Its pretty easy to make it maintain 20 MPG, but that has got to be messed up.
I'm going to take it in to the dealer tomorrow and have them look at it. It's like the electric motor is not working at all.
