Dear gentlemen perhaps it is an old theme but I think I already understand the solution of the problem of the Ford Focus Mio is a Ford Focus 2002 passes 6 months with that problem until I solve it I will tell you everything I started by a bad service to my vehicle Several symptoms that I have seen on the network that did not indicate them well began to accelerate and it is like that fuel was no longer there and it began to turn off I tried to turn And medium cables worked and again with the problem more when it is Quente, reutilizei o tanque e vejo a bomba de gasolina e fiz isso depois de tudo isso, percebi duas coisas que a primeira é que, para mim, a bomba era boa porque o carro foi jogado no carro, então o combustível chegou e foi bem então com o meu primo que é um mecânico que vimos que o sensor da válvula egr. That he repairs it so as not to buy a better the combustion of the vehicle, then he turned on the Chek Enginer but the vehicle was already well of the acceleration, this indicates that this valve must be bought and the largest and most Heat that heats the coil and gradually damages it so when the coil is damaged, the first thing that gives is error in the number 4 piston and therefore you have to change it while the original spark plugs are more heat regulators and do not heat this coil with this to solve the matter there are occasions in which the pump fails but it does not fail and fail It works if you have doubts about the fuel pump, it is easy to see it down a vehicle error code manual based on the central panel that I mean if you press the button that is in the center of your intake dash Precion and the real temperature of your vehicle just have to lower this data from a manual on the Internet and you can know what happens to your vehicle and if the pump has or does not have a precion I Espero ter que colaborar com esse problema com antecedência, espero que ele os sirva e que seja a solução para muitos também dizer que o mecanismo ZTEC é ótimo e você só precisa saber qual veículo você deve consertá -lo no caminho.
