hello guys,
sorry to hijack this thread but I also need some help, I have 2002 st170, when in 4th gear and I put my foot flat down the whole car feels like its out of balance, like when your steering wheel wobbles when the wheels need balancing, well this is the whole car, only on full throttle and only in 4th or 5th gear, sometimes 3rd ........

any ideas ?! anyone
