Manual or automatic transmission?

 

manual

 

Either the hydraulic clutch is not working correctly or the clutch itself is worn out. Start by checking the fluid level in the reservoir on top of the clutch master cylinder. If low, fill with DOT 3 fluid. Because of the excess slippage when the clutch is released, I suspect the slave cylinder is hanging up, or as I said before, the clutch is gone.

 

You probably fried the clutch by now, but try to flush and bleed the clutch hydrolic system first before you replace the clutch.
