Yours sounds like a definite coil pack issue. Coil pack on its way out.
It drove pretty good yesterday, except for that initial "stumble" for the first couple of blocks.
If it were the coils, which I grant you I have never replaced, wouldn't it behave in such a way all the time, and not just when it's cold?
