Revs dropping

[Paradox]

Ive got a 1.2 16v and when i accelerate in 2nd theres a loss of revs and then they suddenly pick up again and you get a small jalt. Also when i go to pull away from a standstill and find the biting point the revs seem to drop and it stalls, sometimes it will just stall at idle aswell. Any ideas?
Thanks
