Ok somewhere while i was driving the car it messed up and idk how. When the car is off, i can pump the clutch and it has pressure, i hold the clutch in, turn on the car, and shift into first, and when i let go the clutch all the way, i loose all pressure and have to turn off the car to receive full pressure again. Weird thing is, if i don't let off the clutch all the way, i can use it. So i have no clue whats wrong. Can somone help Plz.
