Glanza_v9797 Posted July 26, 2018 Share Posted July 26, 2018 Hello all I was just wondering why does my car make a annoying buzzing sound when accelerating after been started?? But it goes away when it is warm ?? Quote Link to post Share on other sites
Paton Posted July 28, 2018 Share Posted July 28, 2018 If your car still has the standard manifold or Cat converter it could be the heat shields vibrating if they are loose. Quote Link to post Share on other sites
Glanza_v9797 Posted July 28, 2018 Author Share Posted July 28, 2018 Would it go away once they were warm ?? Seems to disappear but can faintly hear it when cruising at about 30 Quote Link to post Share on other sites
