Slight idle problem in the morning

[nik patel]

When i start my car most of the times in the morning it idles about 2.5 then slowly comes down after 30 secs. The throttle body has been clean,, and car is serviced regulary.

Any ideas?

Im pretty sure they all do that, its the autochoke or something happens in cold weather, mine does it. Though when the maf needed a clean I did notice it would hang the revs for longer than usual on a cold start, just cleaned the maf and it was fine.

I have changed the MAF about 6 months ago, any other ideas?
