Regular readers will recall that I'm dealing with a bucking/stuttering issue under light throttle conditions. One weird thing that happened was after the indy mechanic replaced the old battery, the problem went away for a day.

With that in mind, I turned on the diagnostic on the CCU while driving home from work and watched the voltage (#24). It sort of fluctuated between 12.7 and 12.9 with the A/C and radio on regardless of speed and whether the car was doing its bucking/stuttering thing. Other posts in this forum maintain that proper alternator output should be 13-13.5 volts.

Is this correct? Do I have an electrical issue? If so, how do I narrow this down?

Thanks,
