Hello, i got a problem, i have a player sprite and i let him move, this is just fine, i use move(2,0 ) and so on for w a s d and he runs but thing is, sometimes he has a few seconds, where he runs crazy fast, and then normal again... hast somebody a clue what can cause that?

You have to make the movement dependent on the passed time. That is, measure the time using sf::Clock and multiply the velocity vector of your object with it.
Alternatively you use a fixed time. A simple way to achieve this is setting the framerate limit or enabling v-sync in sf::RenderWindow. Before you ask how to do this, have a look at the documentation.
