 I appreciate I'm replying to myself.
Tested this morning and the car started and ran just fine without me having to give it any throttle.  Now I just need to drive it more, it's almost criminal how little use it's had this year.  I think I've filled it up twice.
Next job door lock switch and maybe remove the alarm system although I think replacing the former will fix issue with the latter.

I should add this problem is not the same as the one from 2017/18, I’ve done a few thousand miles around Europe since then and it was faultless (until a pothole broke it) I had someone else do some work on it earlier this year, haven’t driven it much but has been funny since then.Mike90S4

Back to my idle/cold start/hot start problem.
I found the vacuum line to the charcoal canister diverter valve was not plugged in. Obviously that's going to be letting in un-metered air and as the O2 doesn't work until it's warm and can compensate means before that happens there's too much air.I'm not really sure how much additional air a little line like that can let in but now I've plugged it back in the car starts from cold without throttle and stays running.  I only ran it for 5 to 10 minutes at idle until the temperature was about quarter of where it normally is, left it an hour and started it again without throttle and it was fine.Actually the first time I started it after plugging the line in it ran for about 10 seconds then suffocated and died (or seemed like it), started it straight away and it ran OK if a little wobbly for about 20 seconds.  I'm wondering if it was running a previous 'more air' adaptation to start with and suddenly with less it couldn't run. 
I'll try again from cold tomorrow just to check it wasn't a fluke.
