morning z owners and lovers....i have a lil issue well i hope little..about 2 months ago i had my clutch replaced.its running great no problems other than recently on a cold start up the clutch feels soft like it has air and it goes almost half way down before it engadges.if i pump it a few times with the car started it comes back up and feels normal...also i have that noise that the z is notorious with the clutch pedal pushed in and turn the car off no noise.if the clutch is released and i turn the car off it makes that wierd rattle noise.so any help or advice would be greatly appreciated.thanks
