If the idle screw is having no effect then i bet the injector seals are shot/hard

injector seals. with it up to temp & running spray some wd40 down into the injector seats/seals if the engine note changes then there is your cause :)

If you have no luck with that good point maybe the Idle Stabilisation Valve is stuck open?

it may be the injector seals because when it was cold it runs very low revs and cuts out.. are the injector seals your talking about the o-rings where the injectors enter the block?

you'll need to reset the Co% after fitting them
