Thanks guys for your input, very helpful.
I am currently using Shell V Power, only been using it for a week and a half, prior to that i chopped and changed. Not using any additives as V Power should have em in it. Problem didn't start after filling up, only started as far as i know yesterday.
Seems weird it only lights up on cold starts then goes away after a few mins of driving, shouldn't it be on all the time if it is a fault. Does anyone suspect coil pack fault that as the engine gets hot the packs expand with heat and close off any cracks. Or am i in the realms of fantasy????
Looks like i may have to sweet talk some Alfa home guru's and pay them a visit to sort this out.
PS.....since getting the exhaust replaced i think the juddering/stuttering has gone, or it hasn't done it to the extreme that i notice it anyway.
