OK, got my car all back together, runs great! Took it out to go cruising nad when I hammer on it, the clutch is hard to push, doesn't release all the way and the pedal hangs up down low for a second. I know my Z28 would do this and it was a common issue on them, but my GTO has been fun until I took it out today. Is it usually just a bum clutch, or is there something else I should look for? It is odd that the clutch is physically harder to push in when it does this.
