need advice on the clutch on my 1988 944.... when i put my foot on clutch pedal slighest pressure and the pedal snaps to the floor board and stays does not come back up....would this be maybe a master or slave cylinder issue??
please help anyone with ideas or insight

 

Yup, either the clutch master or the clutch slave, or the line that runs between them. I highly recommend replacing all 3 items at the same time. Typically when one fails, the others aren't far behind......
