right. at long last ive fixed my focus 1.8tddi. low power issue. after changing fuel pump,turbo,sensors,manifolds, ecu, checking out fuel lines and breathers, ive just changed the injectors from another focus. problem solved. the thing is i had the injectors out and "tested" by a reputable deisel specialist in rotherham, they said they were fine and spray pattern was ok. so long story short ive had the car 3 months and have had many stressed moments. but now the car runs and goes like a dream. thanks for those who took the time to try to help me on here.
