Car shuts off at cold start

[totaleclipse3]

Well guys I just put in a new 16g turbo and the car ran fine for like 2 weeks, now everytime I start my car after it sits for a significant amount of time it idles like crap and will eventually just shut off all together. The only thing I can do is hit the gas until it levels out. Once I drive it around it idles fine and drives fine, its only on cold starts. I have also noticed alot of smoke (blue) coming from the exhaust at idle and when I drive the car. It has always smoked a bit I don't know if this is part of the problem or not. No check engine lights are on. Any ideas??

Sounds like an issue with your FIAV. My start up is similar with my FIAV deleted.

you could have blown the head gasket with the new turbo letting oil into the cylinders, turbo could be bad already, fiav problems, but it sounds like a bad idle air control valve. How much boost are you running?
