I bought this car a week ago and the Bov was fine...loud crisp and consistant. When we had that cold come down this week it seemed to "tighten up alot" and "wobbles out". When it warmed up today it seemed to work alot better:cool: Any comments???

Mine does the same thing. Doesn't bother me as it doesn't flutter more than normal, just more high pitched when cold. I'm sure it has something to do with metal expanding and contracting with temp changes.
