E46 320 ci idles fine but revs jump and drop circa 40 mph

05 346 320 CI 2.2 Auto
Car idles fine. Doesnt cut out. Drives smoothly in almost all circumstances.
The exception is when slowing down comming to traffic, at agout 40 mph or thereabouts the engine revs will jump up and down from circa 800 to 1500.
When I go to a lower or higher speed it behaves normally.
Any info appreciated. thanks
