Hi I've got a fiesta 1.6 tdci 59 plate,now and again I put my foot on throttle pedal to pull off and it cuts out fine when it starts back up.Ive taken it to a garage had it put on machine and it's showing fuel fault anyone had this problem?

No but it is not likely to be a serious problem with the car. Either there is a problem with the throttle pedal sensor which isn't telling the car to squirt more fuel in when you press the pedal or the fuel pressure regulator which is not allowing the fuel pump to squirt enough fuel into the engine. It is more likely to be the former. These engines idle on a minimum of fuel and so any minor error will cause a problem. A third possibility is a slightly dirty injector which stops the fuel from forming a good spray when it is squirted in. you would normally notice this as a "lumpy" idle or a slight hesitation when accelerating from low speeds. It may be worthwhile putting half a bottle of diesel cleaner in each of the next two tankfuls which often helps if that is the cause. You will get it for £4 a bottle at Tesco (often on offer for £2) or about £6 at your local parts shop.

Hi that's what I've been doing buying redex no change so took it to garage and they put revive turbo cleaner in as I ended up with loss of power but that never helped got alot of crap out though,ended up taking it to a diesel garage they done live feeds the loss of power was down to a pressure converter,drive great first week of having it back then it felt like it was going to stoll,then a week ago its stolling every day and its intermittent as been for over a year now I was praying that they would of found fault but its not putting a code in the computer,6 garages I gone to and they can't put a finger on it 😭
