Help?? losing power

Hi,
 
Just noticed I posted in newbie section and noticed I am wrong for doing this!! oops sorry
 
Just started happening lately with my CLK 230 Sport on a R plate.
Sometimes drives fine then other times it will start to lose power, it lurches then pickes up.
One Motorway I can get to 80mph but then if you ask more it will lurch and lose power then it will have a surge and more power will come through....help whats happening and what do I need replacing???? any info greatly appreciated.
 
Kindest Regards
