I'll this when I finish work see what happens.
Simple terms, when the car is cold and needs "help" to get it running, the choke opens which pushes up the idle so the engine generates more power.
That's a simplist view, before someone tells me its cack.
You used to get a lever for this that you would "pull out" when you started your car, but its been automatic for 20 years or so now.

How easy is it to get at this?
What can you clean it with? i.e. some kind of solvent, or just physically clean it up?
This is due to a air to fuel ratio imbalance, either the fuel system is delivering too much fuel into the engine or there is not enough clean air (oxygen ) a few things to look for :
* Faulty injectors (injectors need attention at about 100.000 to 120 000 miles)
* Faulty injector pump
* Dirty air cleaner
* Turbocharger or intercooler faulty
* Problems within cylinder head, valves clogged up due to faulty EGR (exhaust gas recycling unit)
The Forte is injector cleaning, and works best if you fill 50% of a new fuel filter with it, so I'll do that tomorrow.
Will replace the air filter if it looks like it wasn't changed in the recent service - otherwise I'll give it a bang and make sure its not chocka with something it shouldn't be
Hopefully we can remove the EGR and have a look to see what state it is in.
If non of those are the culprit, its probably something serious
