Depends on car since idle speed varies among models but it usually around 750- that would be 12.5 in 1 second.

Idling for a Nissan Pulsar, like any vehicle, refers to the engine running while the car is stationary, typically with the transmission in "Park" or "Neutral." While idling can be necessary for warming up the engine or operating accessories, excessive idling can waste fuel and may lead to engine wear over time. It's generally recommended to limit idling to conserve fuel and reduce emissions. If you find yourself idling for extended periods, consider turning off the engine and restarting when ready to drive.

Engine miss.
When a vehicle is idling, the engine may not produce enough heat to warm the coolant effectively, leading to cold air from the heater. In contrast, while driving, the engine works harder and generates more heat, allowing the heater to blow warm air. The engine temperature can rise while idling due to reduced airflow through the radiator and less coolant circulation, while driving increases airflow and coolant flow, helping to cool the engine.
There can be many reasons why a car surges while idling. Some of these reasons are the computer could be dying, or the fuel injector are giving the engine too much gas.
