I have a 2002 toyota corolla which vibrates when idle once the engine has warmed up. If the engine is cold and been sat for a while the vibration isnt present untill the engine has been driven and warmed up.

Is it a big vibration??
If it is just a small vibration, it could be a dirty injector, if the vibration is bigger (if people know it when your siiting at a light) it could be a faulty spark plug to a bad fuel injector.
Always replace the cheap things first - like spark plugs, and use fuel injector cleaner.
if you bring it to a shop and mechanic is having an off day it could cost alot.
