I took my car to the track once, long time ago. I probably ran like 3 times, ever since every time I hit the clutch to change gears my clutch pedal feels a little sticky and makes a noise like a crunchy, spongy, can't really describe the exact sound. Also when the car is stop, with the engine running for over 15-20minutes I have to pump the clutch like 3-5 times before it allows me to get into gears. I thought it could be the clutch but couple people told me that it might be the slave cylinder b/c the system is hydraulic so I shouldn't feel that stickines at the pedal or noises while pushing on the pedal. Thanks
