this has been there since I've bought the car, however because its not causing any noticeable problems I kind of neglected it till now...
So its an 1998 Levin BZR as some of you may already know, and the problem is that at just over 2k rpm (eg. from 2k to 2.15k), the engine doesn't sound right...
While through out all other range of rpm the engine sounds constant and smooth, at the rpm range stated above some kind of "grinding" noise comes in.....don't really know how to describe this any clearer...
Any1 got idea what the problem might be?
thanks guys~
