What's the engine 1.25 1.3 or 1.4?

Could be the TP sensor(Throttle Position) check it's not dirty or corroded.

vehicle speed sensor i think , to check unplug the triangular shaped plug at the nsr of bulkhead.

replacement usually, most people leave em unplugged  the idle should return to normal, failing that i would go for iscv 

Hi all, Having got Christmas and New Year out of the way, plus a dose of 'flu, I have now managed to get hold of my daughter's car to try and sort this problem out !   Disconnected the flying lead to the VSS at the triangular plug, as previously suggested - still revs to 3000 RPM when cold.  Prodding the accelerator makes the revs rise a bit further but settles back to 3000 RPM.  Disconnected the idle air control valve - it was fully closed - I pushed a screwdriver agains the valve head and it moved inwards slightly (I assume that I was looking for the valve to be somewhat open when cold to give rise to the excess revving).  Both connector this connector and the VSS connector didn't show any signs of corrosion.  (The revving does remain whilst changing gear, but eventually does disappear after a few miles of driving).   So what do I look at next ?

When you say it stays there do you mean it won't drop down at all or it takes a couple of seconds to drop back down. I had a similar problem on my Focus with the revs hanging, I replaced my clutch pedal position switch and it cured it. Ford utilise a system to aid smoother gear changes that make the revs hang for a couple of seconds (so I've been told).

Hi

I have the same problem.
As going along, when in neutral, or as i bring the clutch down (only while moving) it will rev to between 2k and 3k revs.
When i break and am fully stopped moving it will sit back at idle.
Mine is a 1.25 Zetec (V reg)
It has been in the garage twice and he has replaced the speed sensor and then the air inlet valve i believe, but it is still doing it.

Only other bit of info is that it only started doing it straight after i picked it up from the garage last time (did it on the way home) when he had replaced the thermostat as the housing for that had been leaking!
Could these be linked?

Any help appreciated

Thanks
Chris

Unplug the VSS and see if it behaves

Hi Chris123
Sorry, I should have updated this thread with how the problem was eventually resolved (hold on to your Y-fronts, it's NOT good news !!).   I took the car to our local garage (I trust them implicitly !) for a scan, and they diagnosed a duff TPS.   I got a replacement from P***co which looked O.K.   However, the revving problem still occured.   Getting to the end of my wits, I took the car back to the garage - they soon told me that it was the wrong TPS, as the potentiometer worked backwards to that required (still don't understand that one !!  )   Anyway, they had the car for a full week and eventually called in a car electrician to look at the problem.   They did loads of work on it, but eventually took it to another place and had the ECU reprogrammed.   The bill at the end of all that was circa £550  , but the fault WAS fixed and has been fine ever since.   So, probably not the best news for you .........................
