Hi, anyone got any clues what's going on here.

When I'm driving and depress the clutch the revs either don't fall, don't fall far, or actually increase if at low revs:

Doing over 2000rpm, depress clutch, will drop to about 2000rpm.
Doing 1000rpm, depress clutch, revs RISE to about 1600.

The engine stays at that high rev count till I either engage a gear again or it will come down a couple of seconds after I come to a complete stop.

Any thoughts?

I had similar problem with my 2001 focus 1.6 a few years ago. It was a split in a rubber hose. Can't recall exact details for sure, but i think if you look at the plastic inlet manifold on front of engine, beneath it (can see through the gaps in the inlet manifold tubes) there is a rubber hose than runs left to right and curves towards engine at each end, there was a split and it was sucking in air.  I managed to get rubber pipe off and wrap a load of tape round it and get it back on without removing any other parts - and that was very difficult to do. But it cured it.  Of course a new pipe would be seen as a better fix.  Hope I remembered it right, it was a few years ago.

Would that be the crankcase breather hose that connects to the pcv valve you were on about? 

My Ford had a similar issue and then eventually I got the error message 'engine malfunction service now'. After alot of trial and errors found it to be the throttle body, checked YouTube videos and its irreparable. Found a second hand Ford ikon throttle body, also for a 1.6, popped it in, reset it through the obd port and it works perfect

I can’t remember to be honest

The description certainly fits the breather hose. And as it happens, that's exactly where the problem was. One of the bends in the pipe had gone soft and collapsed.

1999 mk1 I drove did that.... absolutely awful....   it was brand new 1.6 or 1.8 petrol   

57 mk2 1.6 petrol I've got doesn't do that or anything remotely like it (thanks goodness)

If you have the sigma/duratec it's the same engine and the one I had needed the breather hose replaced at some point too where it bends at the closer end. 

It was the breather hose. One of the bends was collapsed and had a small hole in it, so ordered a new one.

Wasn't until I took the hose off I saw this on the other side 😮

Pretty much same as mine was. I wrapped loads of insulation tape round it. Ok for years after that. I wasn’t bodging it to save money, but because I needed to fix it quick and couldn’t wait for parts.

Mines was not quite as bad but still caused problems.

i have issue with my car ford focus 1.6 model 2009

am from south africa. The issue is that when i press clutch at any time my car rev goes up. Till am done pressing the clutch. 
so some people say its a clutch sensor is out of position or cylinder master clutch is not working well so i would like to know what could be the problem?

There's two possible solutions described in the thread above. Could be either. Sounds like the split hose is the more common problem, perhaps.
