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. Car will not idle at all without the idle position screwo n the TB turned almost all the way open. The car will crank, and immediately die. Immediately.. cam will hit twice or three times and then die.

 

vacuum leak?

 

Vacuum leak would cause it to die immediately?

Before when I had a vacuum leak it would rev up to 3k immediately and hold.. that was my last problem we fixed.

 

Is the car tuned or are you on stock tune
