Yesterday I was at a red light and thought I would have a little fun when the light turned green. I dumped the clutch and mashed the accelerator and lit up all of 1st gear. I was not riding the clutch, my foot was completely off of the pedal the whole time. The next stop I came to the clutch pedal seemed softer. In a matter of fact i stalled the car the next 2 starts I had because of the pedal feel. Drove the car and the clutch still works good just does not feel the same as before. What could have happened?
