Flywheel chatter or valve chatter?
 

I don't know the difference. I think it's my flywheel or clutch, but im not sure. 5spd manual trans. say I do a rolling stop at a stop sign and leave it in second gear and then accelerate from 2nd at a very low speed, I will get this chattering rattle type noise. of course the noise disappears completely once the rpm's climb to above 1500rpm or so. What is this?















the car otherwise runs beautifully.
