Usually when i step on the clutch is nice and firm, and not loose at all. Today i was driving around and all the sudden it will move down about an inch real loosely, i can flop it up and down and i don't like it. This happened b4 when i was driving around and i just pumped it a few times and it firmed up again. I tried that today and it didn't really help. Anyone have any suggestion as to whats going on?
