I Have A 92 Lexus Sc400 It Runs Great, But About A Week Ago, All Of A Sudden It Started To Shake Very Arruptly, It Stops For A Little Bit At A Stop; But Then It Starts Again, Im Really Worried. Im Not Quite Sure What It Is, I Dont Want To Take It To The Shop Until I Have An Idea On What To Ask The Technicians. Can Anyone Help Me Plz.

How long does it shake and when what cause this problem?

Do you mean vibration from the motor or from the wheels?

Thanks For Responding, It Begins Shaking As Soon As I Turn The Car On, Its Not Vibration, When I Run The Car For A While It Does It More, Im Not Sure If Its The Spark Plugs Or The Timing Belt.

I would suggest you double check the vacuum lines.

Engine related problem....Get a diagnostic check...Check vacume lines, get a tune up, change wires, plugs, caps and rotors...Fuel filter, air filter etc..
