Off the top of my head, I would say it just needs an adjustment... the adjusting screw on the clutch cable can go out of adjustment over time, and its easy to do. Does the clutch fully engage fairly close to the floor?
Pop the hood and find the clutch cable.
Follow it down till the bracket on the tranny.
Find little plastic nut thing with notches on the side, and turn clockwise till the clutch feels ok.
There is a specific ammount of play that arm is supposed to have, and an exact distance the clutch pedal should be from the floor... but I just adjust mine to where it fully releases about 2/3 up from the floor. Anybody have specs?
