I have 2015 ford f150 3.5 ecoboost check engine light on . I SCANNED WITH THE THINKOBD 100 U RECOMMENDED. CODE P219B CAME UP 

AS GENERIC CODE. FAULT CODE NOT FOUND IN DATABASE. I RECENTLY NOTICED WHEN I FIRST START TRUCK LIGHT BLACK SMOKE COMES OUR FOR ABOUT 6 SECONDS THEN TURNS WHITE 111,000 MILES AUTOMATIC.  ANY IDEAS ON WHAT THIS MIGHT BE THANK YOU

The code is telling you that the imbalance is occurring on Bank 2. So you know it's the side of the engine with the #2 cylinder.)

First thing to rule out is an intake manifold vacuum leak into the one of the cylinders on that side of the engine.

Spray around that intake manifold where it mates to the head and see if you can hear an idle change or

maybe see if the short term fuel trim is higher on that bank of the engine, and if it is, does it come down (on Live Data at idle) when you're spraying brake cleaner around a particular spot on that intake manifold?
