Clutch issue, car noob, need halp.
So, I was driving along the interstate the other day and my clutch decided at one point that when it went in, it was tired of the whole engaging - disengaging thing and just decided to hang out where it was at. Revs would build as if clutch was in even when it was out, and wouldn't translate into actual work. It felt very loose pushing in and out after this point, as if the clutch itself were still in and only the pedal was moving. Once I had the car parked, pumping the clutch would build up some 'pressure' if you will, but I was unable to verify that pumping the clutch did in fact make the clutch behave properly, as it would quickly fall back out after pumping.
Any idea what this might be? I am not smart enough regarding cars to really know this on my own, and am not afraid to take it to a shop for fixing because it's probably beyond the level that a Noob like myself can handle, but I was hoping I could at least get some ideas of what it might be (if I do go to a shop, I'd rather not have them tell me that it'll be 50million dollars to replace the flux capacitor)
