Having the same problem with mine as of recent, coming to stop, putting in neutral car was cutting out. Checked and the EVOMS intake had popped off, I've attached it back on but it still can't seem to hold revs. When coming to a stop in neutral it will drop to around 400rpm then spike up then go to normal, also revving on its own in neutral. Let me know how you get on mate, will be getting mine in the garage this week hopefully so will let you know my findings too.

See if it improves with the MAF disconnected.

I Just drove home with the MAF disconnected, had no issues with the revs

When mine was doing this, I found a big air leak on the pcv pipe leading to the inlet manifold ...drove fine with maf disconnected... haven't read the whole thread and maybe you've explored that route...

Edit: didn't have the engine cutting out on me though, just a rough idle and the engine jerking back and forth

SOLVED!
Picked up a new diverter valve even though the old one had no cracks or tears on.
Old DV was a rev c, put on a rev G and it's been fine since, actually feels much better to drive and no madness with the revs!

That crazy, I replaced mine the other day without seeing your post and it's fixed mine too. Original had no rips or tears or anything.

Fickle engines these.  Glad you've sorted it boys  :happy2:

You might want to check your cam sensor too.  Seems they like to get coated in metallic crusties which also affects how they run.  You don't get a code from it though, weirdly.   3 people I know have changed the cam sensor and reported better running.  I also found a 5mpg increase and massively improved idle and off boost smoothness.
