i was at the track and went to shift into 4th and clutch pedal goes straight to the floor. car wont go into gear. then drive the car home without using the clutch. car makes funning squeaking noise when the clutch isnt engaged. then if i slam down on the clutch pedal the clutch engages. and can drive like normal. car sit overnight and go to drive it down the street. squeeling goes away. all of a sudden car wont move until the very top on the pedal than slips like crazy. any ideas?
