Need your Help !!! Idle Problem

i need your Help please.
I chanced the valve cover gaskets and the plugs.
Today i did the first testrun after the car was 2 month in the garage.
And the idle doesn't go under 1000 rpm when i start the car, even when the engine is hot warm enough.
Sometimes it goes up and down like on the video at the traffic light.
Can somebody help what this could be???
Didn't connect something

Thank you .
F.L.
