Idle Stabizer Valve

[Derek Pulvino]

Ok, so then the ISV should have been in an appropriate state of "openess," 
but then I wonder why I couldn't move the valve when I put a little pressure 
on it.  I don't recall it being a high effort endeavor when I checked and 
cleaned it many (4?) years ago.

Hmm, maybe I'll run an output test and see what happens.
