my car suddenly lost most of its power and engine management light came on. after a couple of days without me doing anything.....the engine management light went off but the car still didnt gain any more power so l took it to the local garage who changed the spark plugs, put a new coilpack in and its still the same. a new injector was put in and the problems still there, can anyone help plzzzzzzzzzzzzzzzz
the cars misfiring as well.. only runny on 3 cylinders

hey l have the same car with the same problem it sounds like by ur description, i've been told to have the stepper motor checked & cleaned, it is meant to be a common problem, as for that annoying engine management light, same again, it is a common fault, mine comes & goes, kept having it checked to be told they car not find any problems so gave up & l just put up with it now.

hope u get yours fixed, as for me mines of to the garage next week for a tonne of work,doh
