Parked up the other day and noticed a strange, whooing noise, a bit like someone blowing across the top of a milk bottle - this sounded particularly loud when I put my ear by the front wheel arch. Popped the bonnet, and placed my hand on the air intake and could feel a vibration thru there, so started removing parts of the air intake. Pulled the plug on the idle control valve at which point the revs dipped suddenly then evened out - noise went. Reconnected the valve - no noise. Thought "oh, that's it, must be a dodgy connection", but it's done it again today! Anyone had a similar problem and know what it is? No problems with the engine running, ticks over nice and smooth
