Good day, my problem is as follows:
when I stop accelerating and I am high or under speed, the car goes out, the revolutions go down; Sometimes it recovers and it goes out.

If it has air conditioning
Failure Symptom: The revolutions lower and turn off

thanks,

It turns off when you brake or in resenti without brake treadmade?

Checar gasoline pump pressure

In some cases I am at speed between 50 and 70 km and I need to stop and when removing the speed reaching the total high it goes out, or in its case it loses revolutions and recovers; In other occasions I am accelerating and I will turn and in the change of speed 3rd. 2nd. Another case is a block and I have to stop at the crossing or a stop and the route is very short 100 meters, approx and the same goes out.

What I do is when I am going to stop or do what I talk above, I give it an accelerated so that it does not go out and only the engine is caught.

Thanks for the comment

Look you would have to check several consideration. If the butterfly box is dirty. If so clean it. The idle engine in which this medium is also unbalanced to take it out and clean it and also there is an empty handle that is down the admission multiple and goes to a valve which lets pass the markelings that rot and make it a scaper for the cula suck air. After doing all this cleaning and checking disconnect and connect the battery for a while ... basic. If you don't know, don't touch, fix who you tend to give a hand.
