My Focus has just gone past the 60k point and has developed a worrying problem which I believe is linked to the turbo.
If I pull away quite quickly and work my way up to third gear and do 40-45mhp (when I know the turbo will be working), the car is jerking very noticeably. It feels as though the power from the turbo is being turned on and off very sporadically.
If I was on the motorway and I was doing 70, and I put my foot down to overtake and build up to 75-80, the power keeps coming on and off it almost feels as though the car is being hit by a big gust of wind, as the power noticeably drops, then comes back, then goes again. I have noticed at lower speeds there is a whistle coming from the turbo area, I have checked pipes, can't see any air leaks.
Is there anything I could check, or does anyone have any ideas what the cause is?
A good friend of mine who works for Ford said my lynx engine is virtually bullet proof, so I am surprised at such a (relatively) low mileage, I am getting bother from it.
