The problem is that the engine is running up and down without touching the gas pedal when starting. But when running the car for a while the engine is running ok.

Hi I want to ask about idle air control valve. I haw unscrewed and left connected to the cable. Then I turned the key to see if the valve
is opening. Its has open just a little bit. Like 1mm and a noise was
coming from the valve. Is this normal?
