I apologize in advance for my complete lack of knowledge on cars, I should have spent more time working on them... Anyway, I bought a 98 Legacy Wagon a few months back, and today while I was driving I noticed my clutch sticking when I press the pedal. I could pull it back up with my foot, but it would still stick whenever i pressed again. When I'm in gear there was no problems, but when I was at a stop it seemed like the clutch wasn't fully disengaged, so it felt like it was going to stall. I made it back to my base and turned the car off. I looked online for some help, and then checked for leakage on the master cylinder, and after pumping the clutch pedal quite a few times, i still didn't see any leaks, but the pedal felt normal again. I drove it around the parking lot to test it and everything felt normal. I suppose my question is what type of problem is most likely causing this? I'll kind of need my car in a few days because I'm driving to Pensacola. I'd just like some info before I get it checked out.
