mine used to do it on cold starts and when it was really hot outside and i was stuck at a red light. it would go away when i gassed it to pull away from the stop. i haven't had any chatter since i started using synthetic oil and mid-octane fuel. it happened one other time: when i was offraoding on a really hot day, my fan clutch was burnt out and i needed an oil change. other than that i haven't had the problem any other time.
