Air leak on the joint from the throttle body to the inlet manifold. Reasonably common especially if the engine mounts have given trouble previously.

Also try a stepper motor reset as that may help

Turn ignition on - but don't start car
Depress throttle fully and release it 5 times within 5 seconds
(You should now hear a quite chuntering noise from the stepper motor)
Once this has stopped after a couple of seconds start car
Idle may wander about for a few seconds but should then stabilise.
