1997 Chrysler Concorde - strange temp related problem

    I've got a '97 Concorde (3.5) with a strange problem. It's related not
    to the car's engine temp but actually to the ambient temp. The thing is
    that she runs best from about 45-75 degrees outside. A nice cool night
    in the fifty degree range that car is wickedly powerful. Effortless
    torque, especially if the car is warmed up, shut off, and restarted...
    like if I stopped in a store for a minute or two and got back in the
    car. The farther outside the range the less "pickup" the car has, and
    if it gets bitterly cold outside <5 degrees, there's a 50/50 chance the
    car will flood and die if I try to start it (stinks of gas, sputters,
    smokes, the whole 9 yards). A nice rest in the sun will get her going
    again in a few hours.

    I've hooked her up to the computer, there are no codes and the "no
    start" problem leaves no trace once it leaves. I can't reproduce it on
    cue, either. Two dealerships and a corner garage are stumped. I've
    gotten half a dozen possibilities (haven't changed any, I'm not up to
    spending $$$ on the "shotgun" approach) and re-flashed the computers.
    The only other thing that is even slightly unusual that may be related
    is an occasional "surge" or flutter at moderate acceleration, and
    sometimes when I start it up she sputters and slowly gets up to the
    right idle instead of starting strong. There's no miss, fuel economy is
    in the 19-20mpg range (prob. my foot 'o lead and local driving for
    work), and she passes NY emissions without a hitch.

    Anybody up for solving a mystery? I'd appreciate the help.
