Hi, I have an annoying vibration when i accelerate from around 2000rpm and it seems to go away when I reach over 3000rpms. When I am cruising at 70mph on the motor way the revs sit just under or around the 2000rpm, when accelerate without changing down the vibration starts until u get to around 3000rpm. I have had the engine mounts check, CV joints, had the massfly wheel and clutch done about a month ago. Also had the wheels balance an aligned.
