Rough idle, from using accessories???
I have had the carbon buildup issue for most of my car's life, and recently had the pistons replaced. That got rid of the almost stalling issue after coming to a stop, but I still have a rough idle a few miles per hour before the car comes to a complete stop. What's a bit more strange is the same rough idle momentarily kicks in when I use accessories for the car. This includes the turn signal, power windows, or other things that draw power. What would one conclude is going on here? Could this still be related to carbon buildup even with brand new pistons, or is something else wacked, like spark plugs, etc?

I'm going to have to search for that. Very interested in what that may have been.

Oddly, my idle smooths out with the A/C on. I guess it's the constant higher rpm.
When I got the car back after the piston/engine rebuild, all my settings were still there. But the battery/alternator idea is worth checking. Thanks for your input.
