I replaced the return spring on mine, and it made ZERO difference!
It's not too bad to do, I had the car up on ramps as was servicing it. Removed the heatshield from the (2nd?) cat, and found the old spring snapped off at one end and hanging. I'd bought a new off ebay (although it's been suggested on here that you can bend one end round of the broken one to make a new hook).
Got back in the car, and was a little disappointed that the gearstick still doesn't auto-centre!
Also, in the Haynes manual, for my K11 the clutch pedal should be 176mm from the floor (with the carpet removed), and the free play in the pedal should be 11-15mm. The free play is adjusted as described above, although the manual says you should undo the locknut, pull the lever back until it's stiff, do the starnut up until tight then undo it 3 turns, then do the locknut back up. I've memorised this as I need to do it this weekend! :laugh:
You'll probably want to remove the battery to do this, to get easier access.
