Vibration at idle or at a stop

[kyonic]

Hello I have a 2008 Yaris sedan and I have noticed a vibration or buzz in the car. This happens when I am at a stop sign or light and when the car is idling. Is this normal? Should I take a look at something. Well anyway just looking for ideas. Thanks

I might be wrong on this, but from what I understand and people have noted. The car gets pretty low when stopped. It drops down to 500rpm I think. This weak idle gives you a shudder in the car. The car is programmed like that to minimize gas usage when idling. Once again not 100% confirmed.

Check out the thread at page 2 (below) titled something like "Shakes at Idle" - all will be made clear.
