Buzzing from inlet manifold

ja3142 · 5th April 2011, 11:20

Tinkering around under the bonnet this morning, I noticed buzzing or vibration coming from the region of the inlet manifold. It is quite when the car is idling, but when I blip the throttle (via the cable at the throttle body) there is a buzz as the revs come down.

Any thoughts?

Noisy IACV most probably, I would say, but don't hold me to that.
