ok, check where the wastegate acuater(in the front of the turbo) (don't know how to spell it) is and check if that little hose is connected; then check to see if the vacumm line that runs in the front of the motor is connected to the power steering like needed; then once you get the accordian hose back on make sure that the little hose is connected to the bottom of the accordian; also check if all the vacumms are correct for the heater accuator...

^^run thru the wiring to the jack that goes on the AFM, see if theres any point where it may look rip, burn, pulled etc.

Boost leak? Check your IC pipes. A huge leak will allow your car to idle, but when you try to go, it'll just die on you.

It'll throw a bunch of codes at you too. I didn't bother to check the codes though. Most of them are worthless.
