Hi friends, I have a fiat doblo 2007 1.9 multijet, months ago I had a problem with the DPF, I asked a mechanic to delete the DPF from the computer. OK. My problem is that after my car started to cut the engine when I'm driving, sometimes he loses acceleration and then cuts ... the mechanic who did the service said that there are two injectors that are spending a little more than normal. Can someone tell me if that's right, please? Or if coulb be another thing?
