i have a 1988 5000 CS Quattro, i got in the other day and i pushed in the clutch and it droped straight to the floor, it had this same problem when i got it, and i bled it and it was fine, but now it's doing it again, anyone have any ideas as to how i can permanently remedy this problem?

It also has a problem that happens when i get on er real hard to accelerate, when dropping the RPMs, it'll shutoff, even when in gear.

Any help would be GREATLY appreciated.

 

a far as the clutch goes look for the hydraulic system leaks to begin with ... the shut down could be caused by a vacum leak or vacul leaks are a good place to start lookin'
