Erratic throttle response when cold

Nothing immediate (usually selects and creeps back) so I "think" I squeezed the throttle pedal. After a second or so there was a bit of a clunk and it moved backwards.
Another clunk at the end of the reverse when I changed to Drive - not sure if it was as I moved into Neutral or into Drive.

Headed off and it was "sluggish" going up the hill.

Ignition off, restarted after 5 seconds, all fine. Car drove totally normally from there on

Haven't plugged laptop in yet.........

Same again today, I'm expecting the same codes as before.

The car had been sat unused for a couple of weeks prior to starting it today, maybe I should have let it idle briefly and get the fluids moving before selecting reverse?
