i think my clutch is wasted but im not sure since this is my first and only manual car i have ever driven.....ok when im driving the car and i drop it in neutral the revs begin to increase in proportion to the speed im traveling at and as the speed decreases along with it the rpms decrease remember its still in neutral?does that mean im not disengaging?..................................its crazy but sumtimes shell run fine? when a clutch is bad how can it be good sumtimes?
