Hi All

My auto 2002 has a new and noticeable vibration (buzzing) sound heard within the cabin at exactly 900-1100RPM only. It sounds like it's coming from the engine bay but could be below/behind front cabin. Possible pipes vibrating against something?

It doesn't appear associated with transmission as it appears whether in neutral or drive.

Anyone else experienced this - and located it?

Cheers
Lea
