I just had my ECM replaced by the dealer yesterday and everything was fine. This morning the noise is back!!! Several months ago the noise started out real faint. Then I had stereo and speakers installed, then noise was louder as everyone else described. So I took it to the dealer and they replaced it. But why would a new ECM be just as loud??
