Where are you guys idling at stoplights after the car is warmed up without accessories and without ac? I just connected my obd reader and it's at 550rpm and sometimes 650 rpm. Right around that middle tack. I can feel a slight vibration when it idles at 550rpm. It seems stable, no flunctuation. But it does seem low, when I turn on lights and ac idles at stoplights around 650-750. Where are you guys idling at stoplights without accessories ?

At stoplights without accessories it's right at that small dot at 550rpm. There is a slight vibration in the dash and my seat. If I turn anything on headlights ac wipers etc it goes up 100 rpm to 650 and the vibration isn't there. Does anyone feel this or it vibrating? It seems low and it seems like the motor isn't happy about it. Hasn't stalled or anything.
