As stated this issue happens on cold starts. When the car is warm it has no severe idling issues. I have changed Plugs, coils, VCG and cam sprocket gears While I was there the timing chain lol. Cleaned MAF. Car shakes during that period. I do have ISTA do diagnose however I have absolutely NO CODES. Now on to the warm starts. Starts normally and after 30secs idle abruptly sputters and recovers. Besides that completely normal.
I don't have any misfires as far as I can tell. I have not done a walnut blast of the intake however I do plan to if you think it would benefit. Is Ista capable of live data.

Wait until you get a fault code, instead of throwing parts at it. Ista can read live data under diagnostic requests/actual values
