2007 z06 clutch not comming up
car has been sitting. on first drive clutch stuck to the floor. after i pulled it up it was fine. same happened several times. then it it started sometimes to come up, but not all the way (maybe 1-2" short), in between it was normal. now, after about 50-100 miles, its good. no problems.
im very curious what goes on mecanically/hydraulically to make the clutch act like that and then to "fix itself" (hopefully). i read a lot and talked to people, not really finding an answer, speculations ranging from spring/excenter on pedal to neccessary clutch replacement.
thoughts?

There is a service bulletin/recall that was issued on the C6 for the clutch master cylinder replace. Your master clutch cylinder needs to be replaced. Do a quick search on the Forum or Google and you will find all the info you need.

Pretty easy to replace. Remove front driver's side wheel. Remove wheel well access panel. Disconnect connecting rod from clutch pedal inside the car. Disconnect clutch line going to master; it has a clip and uses a quick disconnect that has a valve that will close when not connected. Undo two nuts/bolts securing the master. Remove and replace with the new master. Re-install everything.
The new part comes pre-filled with fluid. And the hardest part is getting the clutch lines re-connected. Needs a bit of force and is somewhat difficult to get leverage in the small space. You will know the lines are connected once they make an audible click.
I replaced mine a couple of years ago. Took about an hour.
