Screamer

I have recently pulled the head off my B18C 97 spec R engine to put in a new headgasket and ARP stud bots. (yes I am going turbo).

After putting everything together I started having idle problems.
My problems consist of:

1) when engine is cold, my idle flactuates between 400rpm and 700rpm (based on looking at the tack) and eventually the engine just dies.

2) when the car worms up the idle seems to stabolize at about 700rpm, but while driving, if I am slowing down coming to a stop light etc and I put the car in neutral the engine rpms stay at 2000rpm until I stop and thats when the rpm go down to 700rpm.

Please help if you have any solutions.

did you make sure you didn't create a vacuum leak somewhere? intake manifold gasket perhaps?
