Hi Imsael53, good afternoon. First of all, thank you for the answer,

I tell you that the problem of the drop in idle already had it before having touched the turbo, although you carry all the reason for the world in which the air-combustible proportion is now disproportionate to the increase in air. I talked to a friend and poses two options that, as he told me, if it is not one, it will be the other. They are:
1. Bad state of the internal joints of the pump, so you will have to change them and see what happens
2. If the problem persists, it is due to the internal wear of the pump, with which there are few options. Rebuild or replace it.
For my good I hope it is 1, the 2 seems much more expensive ... and, I don't have the economy at its best. I have already spent a lot on him between maintenance and hidden vices that have been giving the face.
Anyway, thank you very much for your help.
