The car goes out when it is in neutral

I have a Hyundai Elantra 99, 2.0 car, American version,
the problem is that when the engine moves in neutral, but this does not happen at all times, however quite often, they could help me with some tips of how to solve this problem

Hello friends I have a rather similar problem but in a nissan v 16 engine E16e goes out when I arrived at the corners they told me that it could be the Valbula iac I love you the same thing happens to you if the alguen can there of my problem with my problem

The problems in the relief are usually Gulpa of the IAC, but not nestarily, see on the theme of the hunday is not specified much if it is automal or mechanical, by the box part this can also happen, this, a loaf that depending on how the fault is if it hits pulls or only suddenly turns off the things to check first the first IAC and cleanliness to the admission body. On the issue of Nisan Deves Checar the same, but I would like Saver if in a normal neutral it goes out, or it is only when the brake is also stepped on.

The truth is that the Nissan goes out when I tagged the brake when I bend in a very closed corner or curve I hope you can help me

in advance thank you very much
