Engine idling too high on start up

I haven't started our EJ9 for a while whilst we've been fitting the new header, decat and exhaust and relocating the battery to the boot.
It started first turn of the key today but is idling at about 2000 and doesn't want to come down again. I was thinking that it's the butterfly in the throttle body that I'd previously polished but when I look at it, it's a snug fit and I did take care not to go near the part that makes contact with it.
Having only driven it to ours before messing with it I don't know if it runs this fast until it reaches a certain temperature?
Any thoughts?

I did check the tension on the cable and seems ok to me. Bit of slack in it.
Got some time today so will start with air leeks and the sticky valve. If that all seems ok I will try the reset.
Not sure how to check that the valve is working properly but will start with a clean and blow some air through it.
