Wondering if anyone has had this issue. When I lift my foot off the accelerator there is a vibrating noise from what sounds like the engine. It doesn't make the noise when idling nor when I am on the accelerator. It also doesn't make a noise when I depress the clutch. It is only when moving! My partner can't figure it out but is thinking it may be the top cambelt tensioner pulley. Would that make this noise. It's hard to explain...sorry.
