Has anyone else had this issue I have about 80 miles on the car since the alternator was changed and its idling around 1100 to 1200 when I come to a stop that was the only thing that was changed at the time. It idled around 850 before. The pulley on the new alternator is supposed to be about 10% bigger than the stock one. Or maybe the computer has not had enough time to relearn since the battery was disconnected for a while when the change was made?

I would think it has something to do with the computer relearning. Mine did the same thing but only for 40ish miles, then it went back to the norms.
