In that case, clamp that hose so no air can flow through it and try it again.

Yes, I’ll keep trying. That idle screw on throttlebody is very rusty and stuck. So I have to be careful not to break it. Or I’ll just break it and thread a new bolt on.

You haven't been turning that idle screw have you?

I have tried to turn it. But it didn’t move a mm. If it would move, I would move it back to its original position.

You don't know its original position, nobody does, they're factory set. They can be put back to their original position by blocking off the air feed to the AICV and setting the idle speed to 500rpm. THere is a locknut and a screw slot in them usually but from the look of yours, it needs soaking in penetrating oil to get the range of movement you need.

Then you will have to reset the TPS adjustment.

Yes I don’t know it’s original position. The locknut is gone. It’s just that threaded bolt that’s left. Pinching the hose to AICV doesent change much in idle performance. Car doesent stall with pinched hose. But stalls with AICV unplugged . It needs adjustments yes. I cannot move that threaded bolt. I can break it and thread a new bolt. Or just wiggle it with penetrating oil so it loosen up. And then do all the adjustments again.
