Default Idle and running Problems - Update

Car cranks and wants to idle if we hold it around 1k rpms.. and then slowly let it down. If we just crank it it'll idle for a second then immediately die. Took it down the road twice and it'll miss at low rpms.. then clear up once we give it some gas. However if we let it come back down to idle it'll surge once or twice and then die.
Car is also hard to start at times, and will onyl start if given some throttle.
IAC has been replaced.. coolant temp sensor has been replaced.. and the vacuum leaks have been fixed. Hole has been drilled in the TB decently large.. and the idle screw has been adjusted to let more air in.

Any help is once again appreciated.

UPDATE. Cam immediately dies upon start up.. it will stay crunk for half a second.. cam will hit three times and then it will die.

Only way car will idle is with the idle position screw turned all the way in.. letting lots of air in.. and then when it idles it will surge horrible.. from 300-1200.. wanting to die everytime it falls. With the idle screw in stock position car cranks and immediately dies.
