Hi, I have a 2006 1.9 TD ? scudo, the problem I have is when I get to between 50 and 65 mph the engine starts to "hold back" as if it is loosing power if I then press the throttle a little further it seems to clear. It sometimes does it when I accelerate through about 30mph but is at it`s worse at the speeds mentioned earlier. Any advice would be much appreciated. Dajam
