Have you removed and cleaned your idle air control valve as they are prone to fault clog up on these vehicles.and control engine revs basically.If not that any codes to give you a clue ? and check for air leaks by spraying around intake area with wd40 and see if revs pick up this will indicate a leak

I have already changed this idle air control valve all be it a second hand one it seemed to rectify the problem until this weekend it has gone back to how it was before, infact worse now as revs up to 2500-3500. are there any other solutions please?

Fit a new one as fitting second hand parts is always a risky business ,well at least with that kind of part.You did say it fixed it.you could try cleaning it but ultimately you are best renewing it.
