I would like to know why Vary Vray the steering wheel

Thanks Miguel for your advice and the message.
A question more Don Miguel what happens is that the car is a 1996 Volkswagen Gol Model, monopunto; when this walking seems as if it ran out of gas or had something stuck and begins as to gargarear it seems as if you wanted to turn off.
The oxygen sensor has already changed and remains the same.

Hi Jase
is likely to have problems with the fuel filter, it seems to me that you have two in your system, the air filter can also give you a similar problem.
LUCK
MIGUEL
