Kaede, I think the prob. that you are refering to is called "rubberbanding" It is caused by worn out bushings mounts, shocks struts, Etc. It is the play in the entire suspension from standing still till fully acclerated. This force rotates the car backwards and the back of the car downwards as the clutch is applied. This causes a rubberbanding of the powertrain and a corresponding shake of the car as the momentary slip of power is absorbed.
P.S. I have been up for almost 2 days. But I think this is what you are talking about.
P.S.*2 Morgan, You know what they say about people who drive miatas. Right ? Haha ha hahah a
