It may be nothing but I have noticed that my clutch pedal is behaving a bit odd lateley. When cruising in any gear, if the clutch is depressed v.v.slightly it tends to move on it's own accord until it reached the floor. I then need to pump it a few times to get it to spring back to it's normal position. I know it sounds stupid, but it definitely never used to do this. Does the cable need tightening, or is it sign that something's about to go? Anyone have any ideas?
