So I have had the car two weeks and loving it so much i've been driving it like an old man - just cruising :-)

Just now put my foot down and the clutch goes weird, bit hard to describe but almost like the pedal drops lower and harder and then goes back to normal when back to cruising. Clutch not slipping or anything it just changes when revving high

Weirdest thing is I had a Mondeo ST last year which did exactly the same thing - anyone know why?
