Friction affects the RPM of a vehicle. Frictional losses in the engine result in a restriction in revolutions per minute.
about 12, 13,000 RPMS.
lower rpms use less gas higher rpms have more power
If you have an engine that idles at 6000 rpms, you need to have it checked - immediately. Around 750 rpms would be normal.
Most cars are anywhere between 750-800 rpms
maybe your rpms gauge is broken.get it looked at by a professional

2 rpms? Your automobile engine probably runs around 2000 rpms. At 2 rpms the engine would stall and stop. However, many automatic transmissions jerk a little bit as they shift gears. I suspect this is what is happening to your Pathfinder.
It would depend on the gear ratio and transmission. stock tires 235/70r16: auto(O/D) with 3.55 gears =2160 rpms auto(O/D) with 3.73gears = 2270 rpms manual with 3.73s = 2360 rpms
The engine coolant level is low. Add more and the pump will be able to move coolant at the lower rpms.
