Its very strange. Started about a week ago. If the clutch is under a load, it feels solid at the lever. If not under a load, it looses its feel and has about 1.5 inches of free travel. It didn't have any till last week. The engine and clutch only have about 4500 miles on them. It doesn't slip at all, and still seems to slip into gear easily. WTF? I changed the oil and pulled the clutch cover off yesturday. Checked the springs and plates - all seem to be perfect. What has happened?
