Sooo Close

["Jeff Goldberg" <jeffgold@erols.com>]

No takers first time around. Can anyone help me understand what's going on
here so I can get this car to the point where I no longer lift the hood at
every stop?
It is so close to perfect but something is missing. Can anyone explain why
the car behaved as it did, offer any suggestion of next step or just refer
me to a good shrink?

TIA,
