Hi New Member/running problem

[redmicra]

Hi all new user to site.I have an L reg micra 1.0 16v which i use for work.Has 107,000 on the clock runs sweet as a nut apart from when you pull away or come out of a roundabout,if you put your foot down there is a flat spot/hesitation but as soon as it clears it is fine.I have fitted new plugs,air filter,fuel filter about 1,500 miles ago.Any advice would be great.Thanks Keith
