well, once in a while the clutch will go from soft, like it should be, and then one day it will be pretty damn stiff, and then go back to being soft, no problems with grinding or and cant get into gear, just the pedal will be stiff one day then be normal the next, could it possibly be that there would be air in the clutch line?

 

just rebleed the clutch and see if it continues to do it....

 

well just rebled it, see wat happends it a couple of days, the stiffness went away
