Car Shudders at Acceleration

[Creditcard]

Hi All,

Long time reader, first time poster.
I own a 2007 Yaris TS and I have a question about it's traction control.

When I'm accelerating a bit harder than usual and the traction control light comes on, the whole car shudders very violently until you get your foot of the gas.

I was wondering if this is normal behaviour? I could imagine that the traction control applying the brakes, and me stomping the gas isn't a very good combination..

Thanks.
