Well since I live 3 hours away from R/T tuning they emailed me a manual relearn process which I had Nissan do because I received the email the same day the car was in for service. When I got the car back everything seemed fine until the first attempt to turn on the AC. As soon as I flipped the switch the car started this issue and has been like that ever since. I even took it all the way back to Lansdale PA (r/t) and of course the car wasn't doing it when I was there so they were unable to fix it but the car eventually did throw a code which was for a low idle. So it's my belief that when the car went through the manual relearn process the idle was set too low but r/t disagreed. All I'm sure of is everything was fine before the relearn and now it seems like it's going to stall out at low rpm's and runs really rich at times
