engine miss on cold start

Hi When I start the car it runs idle fine and even holds the revs nicely when I push them up a little. But when I go to pull off there is a miss for a single moment then it runs fine untill I get to the next junction at the end of our road and does the same again when I go to pull off. Does not seem to be there after 10-15 mins of running time. What could this be? TIA Ricco

misses on pull off when cold 

Bump - Sorry still have this problem and its getting a little worse as the weather gets colder. DOH!

sounds like an ignition HT problem , start with a new set of volvo spark plugs ...
