i have lost pressure in my clutch the resevoir is full but it will not engage at all. it sat for about 2 wks after we bought a new car and this is what i came back to. it had been reving wierd when i got on the accelerator hard but babying it kept it from occuring ,staying light on the gas after shifting. is there any hope to solve this myself or is my clutch completely shot.any assistance would b greatly appreciated

Clutch MC could be bad due to an internal leak.
Slave cylinder could be bad.
Clutch could be worn out.
