Hi! Can someone help me? The following problem: For 2 weeks my Fiesta Bj 90, 1.1L, 50PS has been mucking. He didn’t want to take any more gas in some speed ranges until when he was cold and was always about to go out. Last Friday the performance then collapsed and he ran instead of 120Kmh only about 90kmh. I thought it was the weather, tried again tomorrow. Next day, got in, hit, drove off, engine drunk. Organ organ, didn’t come. My father meant that I had to go n air filter times should be done. said, he jumped on. short piece driven, drunk again. organ organ came short and ran on three pötten. known asked: ignite candles change! now new air filter worried, new ignite candles come in. He now does anspriengen, but still runs on three pötten and absift when I give gas. have already cleaned everything on contacts, plugs with contact spray. I no longer know what to look at now! Maybe someone h 11th???? Daniel
