For a few days now, my Ford diesel has been pushing at speed. If I speed up very strongly, then it’s less powerful when I speed up gently, the jerking is stronger. Taking away the same effect when it comes to gas. The effect doesn’t seem to depend on the speed or the engine temperature. I’ve always driven petrolers, so I had similar appearances when the idle was “too lean”. The mechanic then mostly turns on the right screw, and OK was. At the last DEKRA here in France, the technician said that he sees leaks on the Krafstoffpump, I don’t know if that’s a clue for you. Melt plugs have changed about two years ago. The car is mostly driven over a distance of 2×30 km daily, because we live in the country. Does anyone have an idea, which I could maybe even look at myself first? Cleaner supplement for the nozzles or something like that? Or… will this be a really expensive repair?!? I can already deal with a screwdriver,(I didn’t find anything expensive here from the forum), but I can’t really ask for my girlfriend about the French.
