I have asked this question before, but never got a clear answer. This is the first winter/fall i have had my z, and this is new to me. Heres what happens... I start it up, let it sit some, (btw the longer I wait for it to warm up the less it whines...) then when i start driving, through the gears it whines and when I really get on it, it whines even more. Is this something the z does ...
