Right so timing belt and tensioners changed ,engine flushed and oil changed,new iridium spark plugs and air filter fitted but still got a judder.
So I decided to buy a coil pack and go through them one by one starting at the back taking out the old one and putting the new one in,taking it for a drive to see if it still juddered if it did I put the old coil back where it was and moved the new one to the next .
Anyway as sods law dictates it was the coil pack at the front, the last one I tried but bingo no judder so after quite a bit of cash and a lot head scratching its finally cured,
Thanks to all that commented and helped me diagnose my problem .
