cold start idle problem

hi there people
i have only had my focus for a week and to start with it was ok, but now on a cold start if i rev it the revs dont drop down they stay at about 2500-300 rpm and then after maybe 20 secs they come back down.this only happens when the engine is cold! any ideas???? i have searched for posts relating and i did find one which mentioned air leaks as causes of idel problems but it didnt mention engine temperture.it did mention air leaks though! the guy said that sometimes air leaks can be heard as whooshing sounds when you rev up, i can hear this sort of noise when changing gear and putting the revs back on! it sounds like a turbo charger dump!!! does anybody know what it could be, or what it is?

i meant 2500-3000 rpm, and i made it unclear that the noise i am hearing is a whooshing of air when i first stick my foot down. i fear that my bad luck is haunting me again cos my old car broke down with fuel injection components going wrong all the time!

When I took my 02SVTF in they said that was normal but then they released an update to the PCM or what some call ECU. Didn't entirely fix my problem but it has subsided partially.

higher idles when it is cold is normal. This is built in to the control strategy to promote faster light-off for the cat and to heat the engine up faster. Any revving of the engine will force it to come down much slower in cold weather.

im still a bit paranoid about it today becuase i have noticed that the revs go up on their own to 2000 rpm ish, but its still initiated by revving, then they drop down to 1200 ish and then they slowly climb to 2000 until i start moving again.

Here's a thought: just don't rev it for the first 20 seconds.
