   does it for how long? Does it settle down after a little bit?
   
   Try cleaning the icv as its the simplest reason for a dodgey idle..

   It might need a new icv but not 100percent sure if if settles after bout mile mine seems to only last until I pull off before I cleaned it

   Cas you got your foot on the throttle.
   
   I kid.
   Maybe its related to the automatic choke? I can't really explain in depth. But on my classic mini with manual choke that's how i warm my car up. On about 2000-3000 revs for a few mins then it starts to tick over at about 1100. But don't take my word for it.

    it something which raises the revs a little when you start up a vts from cold mate
    
    if it was me I would plug the car in diagnositcs and see what the sensors are doing and do tests etc but im guessing you wont be able to do that mate.
    
    I would get a mate with the same car and swap sensors over one at a time to find the offending part, that way you are not wasting money on parts chasing the faulty part as that can get very expensive
    
    without hearing your car theres a possibility that you have an air leak somewhere around your inlet side that leaks in air to raise the revs and when you car is warm the leak closes off due to the engine and components expanding. If this is the case you should hear a faint hissing when cold
    
    hope this helps
