Chevrolet Monza with varied problems

In the video I see that the Mescla Eye is broken down with the temperature sensor if you can change it is cheap and it is not others to subtitle it greetings

Thank you all for your councils,
I have solved the problem so far, but not quite, at least now it does not go out but if the revolutions are lowered when stopping at a traffic light but then they rise and stabilize. (Only only on some occasions). My conclusion is that the accelerator's piola should be chopped, which does not let the acceleration butterfly regularly regulate the tolerance of the same sensor to tolerance causing a lack of control in the maintenance of RMP.
