Engine Misfires

[topspin]

Hi all
My 2 year old wagon r misfires and does kangaroo type jumps when accelerating quickly,from rest(usually between 2500-3500 rpm),people who sit with me think i'm running out of fuel!.The problem only occurs when the vehicle has done about 3 miles and fully warm.The vehicle has done 40,000 miles and i have had the problem for the last 10,000.The car runs without fault at speeds above 30,just poor when accelerating.I've taken the car back to the dealer,paid for diagnostic checks,and they say i have no problems.I have changed the spark plugs several times using recommended type nad have noticed the one's i take out are slightly blackened.
Any comments from members who can relate to the above,would be appreciated.
Thanks in advance.
