Should your RPM be at 0 when you turn your car on?
Most engines idle between 500 and 750 RPM in order to stay running. RPM’s explained and a refresher on 2 laws of motion. The “little below 1000 rpm” is the engine idling speed. At 0 rpm the engine is not running and must be started before it can produce any power.
Why does my RPM stay at 0?
This could mean a vacuum leak from a hose or the intake manifold itself. Or, commonly, it could be that your Idle Air Control Valve is clogged or not working well. The engine monitors via sensors how much air is coming in vs engine speed and uses that to control fuel injection and ignition timing.

Your car engine is cold, your foot has been taken off the gas pedal and the engine is running very rough. Stalling may occur here. 1.
What happens when the idle speed is too high?
The ECU then uses rpm feedback to position the IAC. If the engine idle speed needs to increase, the IAC will open a few steps, allowing more air into the engine. Or, the IAC motor will move close to fully closed if the idle speed is too high.
Is it bad for the environment to have a car idling?
Car idling is bad for the environment. Keep the car maintained and service on a regular basis. Disconnect the battery. Keep it in a dry place with its terminals oiled. Spray oil on the spark plug sockets after removing them. Then, put them back into their slots.
