Toyota Corolla 2000 accelerated

It turns out that I have a Toyota Corolla 2000 Motor 1800 cc and this is constantly accepted without fluctuating at 1200 rpm, I already check the accelerator cable to see if it was not badly adjusted or very tense, and it was not so, I saw the screw that regulates the opening of the butterfly or strangler and it was loose without a topar, I do not know if it is the sensor empt that this bad response.

Hello, you can check the emptiness hoses may be broken or loose, also check the idle actuator

And the idle actor who mentions where I place it specifically in this type of car, since where the butterfly or strangler is located above this the empty sensor, to the right the butterfly position sensor and below there is an elective actuator of water that comes from the radiator between two hoses that are under the butterfly and the pair of this actuator
