have you ruled out a bad diode in the alternator? i would also like to see 2 fresh batteries on it to see if 2 batteries inline would dampen the electrical spike so to speak.
is this an early 3rd gen with apps? maybe timbo can help you .
did you wiggle the ignition wires?
there is no way to have the dealer "test" an ECM.
