Re: Rough idle after charging battery
Tim, my '02 Z/28 with LS1/4L60E did the exact same thing a few months ago when I replaced the alternator and battery and it was only down for a couple hours. Seems like I remember the voltage gauge swinging wildly like the PCM was oscillating the charge command to the alternator and I could hear the fuel pump going up and down also. I don't think it's the PCM resetting because imaging if they all did that at the factory the first time they fired up or lost power...that would be one poor base calibration. Just like you, power cycled it and it was right back to normal and I've had it down and even the PCM battery fuse removed before without it doing that.
