Hi All,
I have an IS200 (02 Plate) and on a recent motorway journey I started getting very bad shaking at between 45-65 MPH. Touching the brake when it's doing this is extremely scary - the car really wobbles and shakes like crazy. Below those speeds everything is fine, and above those speeds it seems to be fine. To add to the woes though, every now and then at high speed 70-85 I hear a noise from the engine that sounds like it's revving slightly higher (but the rev counter stays the same). I had the wheel balanced and alignment checked and re-done - but still the problem continues.
Any helps, ideas or suggestions would be much appreciated.
Thanks guys,
Lee
