Mine has been a white smoke
Roll Call - Alpha Turbo Smoke Issue

What color is the smoke for the first 90 seconds?
It is dark, it's hard to tell if it's blue or black. Is it possible that it is due to a rich mixture that is more prevalent at Idle?

Mim buddy that is in Alabama. They wait until 32* to worry about ice. They are not like us down here. When it gets below 40 we are hunkered down waiting for the snowpocalypse.
My Wife is from the Rio Grande Valley (McAllen, TX). If temps drop below 70F, everybody bundles up like it's freezing!

Yep. You are probably seeing the enrichment of an open loop idle tune... I believe it doesn't use the O2 sensor to make calculations. It uses the fuel table and the throttle position. So it would do what your seeing when it's first started. No worries as long as the smoke goes away after its warmed up... -
Here is what you don't want to see. This is a couple pictures of oil smoke. Notice the bluish gray color...
I am betting you don't have oil smoke. And that is a good thing... Fuel smoke is a good thing. It means your not running lean....

Exhaust Color Diagnosis
Blue/Gray Smoke: Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber. These are possible symptoms and causes:
Valve Seals: Leaking valve seals will cause blue/gray exhaust smoke.
Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder.
Piston Rings: Worn or damaged piston rings will cause blow-by, resulting in blue/gray smoke.
Worn Cylinder Walls: Worn cylinder walls cause blow-by, resulting in blue/gray smoke.
PCV System: A stuck closed PCV valve causes excessive crankcase pressure, resulting in blue/gray smoke.
Black Smoke: Black exhaust smoke is an indication of a rich fuel condition. These are possible causes:
Fuel Injectors: A leaking or dripping fuel injector will cause a rich fuel condition.
Fuel Pressure Regulator: A stuck closed fuel pressure regulator will cause a rich fuel condition.
Fuel Return: A restricted fuel return line will cause a rich fuel condition.
White/Gray Smoke: White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes:
Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber.
Engine Block: A crack in the deck of an engine block near the coolant jacket will cause coolant to enter the combustion chamber.
Head Gasket: A damaged or blown head gasket will cause coolant to enter the combustion chamber resulting in white/gray smoke coming from the tailpipe. -
Thanks! That puts my mind at ease. I'll keep an eye on it. It seems to clear up a bit if I Rev it up.

WOW!! That is informative - I always thought smoke meant bring it to the shop

Yep. It will have a bit in the turbo and in the line that seems to come out when you break the line loose. It will be enough to either run down your arm or screw up a clean shop floor.
