I have a 93 del sol si and when i drive the car for a while it seems like the clutch doesn't disengage all the way because it is hard to put the car in all gears and every once in a while i can feel it grind just a little bit. When i let the car idle for a couple of minutes and drive the clutch feels normal and its easier to put it in all gears but gets worse after driving a while. i've bled the clutch line and the fluid was black (tried to get most of it out) but i was wondering what would cause this problem. any help is appreciated .

 

Yes that could cause it. Make sure you get all the air out. And make sure that you're not leaking fluid anywhere. Also try searching, this seems to come up a lot on here.
