Thank you all for your help ... Until now I make a state report of my car ... Solve the subject of the PCV valve (do not ask how mujajaja) the slowdown is completely stabilized, even left it up to 500 rpm without the engine vibrating or stopped (current idle 800rpm approx), the car is a bullet, I can make it lift from 0-160 km/h without problems, I have even done it. Reach at 190km/h without problems ... but here the details that I have ... When you reach a corner or when the engine is suddenly stopped, it tends to stop it in a civilized way in 1st tends to give some pulls, and when turning to the right the car tends to give pulls too, and when it stops turning it is normalized ... now I will check the fuel line to see what happens ... greetings to all
