Default Uneven Idling??

Mates facelift classic has very uneven idling, goes up and down, quite ryhthmic really. ECU showed dodgy knock sensor which he replaced but still idling funny.
Any ideas??

With regard to the DV... If you get no joy with the other sugestions try fitting an OE Dump valve. DV may be faulty, its pretty common..
