Hi,
I have a few problems need to resolve and would appreciate the help.
It's a escort van fitted with with an escort 1.816v si engine.
Now the first problem is on start up the revs drop to nearly stalling point then shoot up to around 2000 revs, I'm assuming this is the idle control valve but wanted another opinion, after afew minutes it will idle fine.
Second problem is when accelerating in 1st, 2nd, 3rd and then taking my foot off the pedal the van jolts abit from front end and a noise comes from front end, sounds like a belt slipping a medium pitched dog yelp describes it. It doesn't do it if I really gently take foot off accelerator.
Help would really be appreciated

Could be the idle control valve, does it ever cut out on you? I can't reall offer any help with the other problem but I'm sure someone with more knowlage than me will help you out soon.

Well I've only owned it for a week but no it hasnt cut out on me, I have started to push accelerator and hold revs at like 2000 as Im not sure how bad it is letting the revs drop an rise constantly.

It won't cause any harm letting the revs go up and down. A mate of mine used to have a zetec that did exactly the same, I can't remember the cause now but it wasn't much serious. I think these have a plastic t-piece in a vaccuum line under the throttle body, these can crack leading to poor running. Could also be Idle valves are common on the zetecs along with air flow meters. Unplug the AFM and try again. If it runs better then you've found the problem!
