Rough Idle, sometimes idles, sometimes dips low, sometimes dies?

[idkiliketurbos]

Hey guys, I just got my car driving and running again from a head gasket and timing belt job and while driving it runs good. Most of the time it idles at a good rpm, rough most of the time. Sometimes it will dip down to 500 and surge +or - 100 rpm. Tonight when coming to a stop it died 2 times from dipping so low. I did a vacuum delete on the car and that means way less places for it to have a vacuum leak from. The throttle body shaft seals are relativly new, new injector seals, new intake manifold gasket, new biss o-ring, new throttle body and elbow gaskets. I did notice that on one of the stock injectors that the black tip on one of them was nearly gone, could that cause one of the injector seals at the head to leak masive air and cause a vacuum leak?

I'd check for boost leaks honestly
