    Well it is interesting that this happened at the same time as the PCM re-program, since the PCM also acts as the voltage regulator for the charging system.

    Intermittent problems are tough because you need to jump on them while they are happening. I suppose you could take it to the dealer and have them do a diagnostic on the charging system to see if they spot any irregularities. A change in amperage for instance might not show up on a dash voltmeter.
