Clutch pedal flaky, gotta put it to the floor, Sometimes is works, sometimes it doesn't Options

[sh0x]

95 GT convertible (5SFE), 141k miles, 5 spd manual, all factory except SRI. Car runs like a top except for a code 71 (CA emissions, EGR failure.) Not that I think it's related.

I had the clutch replaced last year, about 10k miles ago. Now my clutch has been requiring more and more travel. Pedal height and freeplay are set correctly according to factory specs, but now I have to pull the top carpet back and put the clutch pedal all the way to the floor to change gears. As soon as I take it any distance off the floor, the car starts to roll. Sometimes after it warms up it doesn't want to shift into gear (esp. into 1st) or grinds a bit (esp. into 4th.)

Yesterday I thought I was going to be stranded but after forcing it into gear and getting it home I left it sitting for an hour or two and have had no problems since (other than still needing to put the pedal to the floor.) I'm guessing something is wearing out. Any ideas? I replaced the slave cylinder last year when I had the clutch replaced as well.

Thank you in advance for your input!
