Sounds like your clutch is dragging. Does it release closer to the floor or at the top? How is your clutch pedal oriented with the brake pedal? Same height? You may not be giving enough throw with the clutch pedal (it is adjustable from inside the footwell). You should also have someone depress the clutch while you are under the car. You can then observe the slave cylinder to ensure it's shimmed properly to allow the right movement. Or if it has an adjustable rod, then move it as appropriate.
