Hi, i have just brought a vr6 highline, which had an MOT yesterday (by the garage i brought it from) when i go above 60mph i get a large amount of vibration, making it impossible to go above 85mph. this vibration only seems to happen when accelarating, if you coast it nearly disapears. the car is an auto if that makes any difference. Has anyone had a similar problem? i have checked the tyre pressures, and spoken to ATS tyres, who drove the car, and whislt they think the tracking may be slightly out, it does not sound like a balance issue. they noted that the steering seemed very notchy, it is
