My fiat fiat fiat is accelerated

Hello I have a question I have a big problem with my Fiat Doblo 1900
without turbo. The problem is that it accelerates alone when I feel like
I have changed the accelerator pedal and the
GRS valve remains the same and it is still the same as the fault light does not know what
it can be if you can help me thanks

Hello, that light indicates just some problem in the injection system, you said that you annulled the EGR, it would have to see if it turns on that or if it can guide you in some other failure that relationships the problem. It is best to start by Scanner the vehicle and based on that start analyzing .. greetings

Hello thank you for answering a scanner and put me a fault of the accelerator pedal or the valve. E Cleaming the valve the pipes that go to the grs spin admission and put the new pedal of the accelerator but it is still the same other to me that it can be of the pressure regulator that goes from the air filter to admission to admission but I am not sure that I have already spent money
