sound's like it's overfueling,imo the first thing to change would be the cts,then see how that goes.

cts controls the coldstart so it could be keeping the engine on coldstart which could explain the overfueling and high idle.although is still shouldn't be at 1500 rpm.

If he's changed the AFM then take your time to look round all of the hoses for a Vac Leak. When mine had a split it idled irratically.

I'd be runing to the vauxhall parts desk to get a nice new CTS next, should get change from a tenner

Then take off the ICV. It's a metal cylinder thing that is a pig to get to. Make sure that it is nice and clean, I cleaned mine with some Brake cleaner then a bit of WD40 down there and put it back together.

What induction kit is on there? Is the filter nice and clean?

Have you checked ICV to see if its stuck open?
Try squeezing the pipe with go's to the top hat an see if the rev's drop.
As for the smoke, is it when you nail it you get smoke and then it go's away higher up the rev's?
Could be your valve stem oil seals, had it alot of high milage C20XE's which have had a hard life.

My money is on stuck open ICV and valve stem oil seals.
