also a clutch problem

[white90gsx]

I bought the car like this..when im racing or just shifting fast the clutch seems to ride itself inbetween gears now i thought that the clutch was slipping or going bad but its not because i can go up a hill in 5th with a lot of load and the clutch dont slip or i can dump the clutch and still wont slip but when im racing it seems like im easing the clutch out in between gears and im not i dont know what it is?
