Question, the car is warmed up, drove a little. I stopped in the Neutral position, the speed showed on the tachometer as it should be 0.750 rpm. I move the gear lever to Parking as the speed rises to 1000 rpm. Again I transfer to Neutral, decrease to 0.750, to Parking and rise again. Drove a little, turned off the car, started it again and everything was back to normal. At the same time, no warning lights came on. What would that mean?

Your questions would get more views if posted in a more relevant forum category.
If there were no warning lights I think the engine management system determined that was the required RPM.

Possibly the engine idling up because the electric fan was on?
