When idle, cold and warm (sometimes it doesnt do it at all) the cabin will vibrate quite violently (bearing in mind I'm used to driving an old Astra diesel which didnt vibrate at all). If I touch the accelerator it goes away. What's this issue? I've read a few things but most point back to engine mounts?

And the gearstick, 3rd and 5th is the worst, but the stick moves all on it's own when you accelerate. Surely this cant be normal?
