    As per edit note

    For the noise, when it is happening at idle, open the needle valve gradually and does it stop?

    Also check vac lines as you said and at idle have a look and see if the actuator rod is in the up most position (lever hitting stop). Check to see if the actuator rod lock nut has not come loose an allowed the actuator rod length to increase. If too long eng will become very laggy and exhaust will get more of a throaty sound and higher EGTs. The witness line up marks on the the adjuster thumb wheel to actuator rod will indicate any movement. Best leave it alone if looks like it has not moved.

    Thanks Bidja, I'll check all that out over the weekend. Much appreciated.

    Is it manual? If its manual then thats the standard gearbox chatter. Sounds like rattle or pinging .

    Seems this is normal. It was enhanced by the vacuum leak that I had. Once I fixed the leak, the rattle almost went away.
