(e.g. when I go up a hill, and gear is too high). When cruising on level road, the rattling sound takde.  I was told that it is most probably air-fuel mix needs to be reset (or something to that effect). Is this correct? And can this condition effect power and fuel consumption? And if this is true, can I have any (decent) mechanic readjust the mixture/fuel injection or must I look for a qualified/official bmw workshop/mechanic, to do it?  Was told it shouldnt cost more than RM100.  Your wise words would be greatly appreciated.</p></blockquote><p></p>
