i've been fiddling a fair bit with things on the car, the other day i had my head under the hood and was giving the motor a rev,

normally if you rev it and hold the revs up (guess around 3500rpm) it will lean to one side and stay there till you release the throttle again..

i found with mine at the moment it will actually rock side to side like a vibration (pretty large one though obviously)

um, hoping it's the gearbox

but just curious about it wondered what peoples would say
