Clutch problem
 

Didn't know where else to put this so here I go. I have a 07 Wrx with 84k miles on it. Recently I noticed some slack in the clutch pedal. It moves a bit before it finally engaged when I press the pedal almost all the way down. Well today it actually got stuck and I'd have to push it back up with my foot after every shift. What do you think is wrong? Does it need more fluid, or do I need to replace the clutch plate? I need to know asap. Thank you!

That'd be air in the system. More than just topping off the fluid, though will need more fluid, you need to bleed the slave cylinder. It's something you can do with a friend, some tubing, a dry bottle and a flared wrench. Google is your friend as to how. Good luck.
