Hi Zergio73
the comments you have received are the most successful, I add one: look for the diagnosis of another mechanic, the one that gave you and I leave you with your mouth open I do not believe it.

Ha Zergio73, there are many steps and things to check, but let's start with the start, listen and see, you have walk the vehicle and listen to the exhaust of the exhaust as the gases come out, they have to leave even, that is to say continuously, if it sounds like it is to say it comes out gas and it is cut, it makes like a pop while the gases come out and also the smoke that can grate or not, in the high Injectors Sensors or engine in general, but first Czech that and let us know.

No, the vehicle sounds even and soft in that aspect is fine

Gentlemen another fact seems to be a problem at the air entrance to the engine, you think, why do I disconnect the hose you have before filter and it works at one thousand wonders

It has a flow, when it improves is due to bad mescla but can be Barias Cosillas, the oxygen sensor checked it?
