This is similar to what happened 2 weeks ago after the battery was replaced.

Twice now the electrical system has been messed with and the problem seemed to go away briefly, but I'm still scratching my head over what that means.
The charging voltage is about right (depending on alternator size -- if stock, should be 90 Amps). Perhaps the stuttering problem is not related to the electrical system at all.
