Repeali very high in Ibiza 97

Greetings to all and happy year.
My problem as the title shows, is that my Ibiza 1.4 Injection has too high slowdown, reaches 2000 rpm. And until it heats up, it fails to accelerate it. I started everything when cleaning. With cleaning carburetors, air entrance, accelerator butterfly, etc. I know if it takes slower valve and if it will be the one that fails. But I am desperate. Imagine what is moving in the traffic of a city with the idle! If there is no other left, I will have to take it to the mechanic, but with the current situation, the money is scarce.
If someone has an idea of ​​how it is repaired. I thank you in advance

Hello partner, your car has to take idle valve you have to clean it in time when they are somewhat expensive looks if you do not have any broken sleeve or the time to clean it you have touched some look under the admission collector. A greeting. He signs and happy year.

Thank you for answering, I will take a look, greetings.

Of no man for this we are here to help each other. A greeting.

Hello again.
Well, this weekend I reviewed the car. Looking for the aforementioned idle valve, but apparently it does not have an independent valve that can be removed, as many mechanics
have. In this Ibiza behind, right next to the admission mouth it has a kind of box the size of two tobacco packages with a screwed plastic lid, inside plastic gears. I don't know where the happy valvulite will be. It seems that what would have to be changed is all complete, but that is worth a paste, and I am short. If someone can give me any idea would be appreciated.

greetings.
