Revs blip

Hi all,



Just wanted some advice, working through the niggles on my new 2004 1.6 petrol 45.



When the engine is cold, or just up to temp - when I let off the throttle to slow down, the revs and engine blip down like a missfire, but nothing that severe.



Put the power on and all is normal, and leave the car to warm up for 5 or so miles, and the problem goes.



Any ideas?, i was thinking maybe MAF?



Cheers guys

Andy
