focus rs starting problem

[chriz1]

I seem to have a bit of a problem when starting my car from cold.I press the button to start and it takes its time to start and when it does it runs really rough and revs rise and drop and sounds like its on 3 cylinders,after 10 seconds or so its fine then and starts good when warm.
Its running the latest engine map but still struggles,no engine mods either any one got some kind of idea??

its a 53 plate,il check the battery voltage this morning now and see what it says.
Im also going to try and look for the idle speed control valve and get it off and give it a clean with carb cleaner see if this helps.

Put it all back together and it certainly fired up with more oopmh!!!
So wait and see really.
