I had the same problem with mine.
But i had a new clutch fitted and only after this did it occur.
i tried everything
Fitted new breaks front back,
(including disks, pads and calipers)
and it was still the same
so i took the air box off, look at the clutch cable
loosened it, and tightened
then i saw another cable underneath
i loosened that, then tried the car, and it was like brand new, no problems at all
hope this helps
