I get this clunking noise sometimes at idle, and I feel clutch pedal vibrating a bit. When clutch pedal is pressed, clunking stops. Also sometimes, when car is stopped and I want to engage in 1st or reverse, pedal gets stuck and I have to bring it back up with my foot. When I accelerate, RPM revs but speed seems to be a little late. Apart from all that, switching gears while accelerating is totally fine and biting point too.
Is it the sign of a dying flywheel? How many miles can I drive before changing the whole clutch and flywheel?
