Need Advice! 2017 Honda Ridgeline Bank 2 Issues

2017 Honda Ridgeline with the following codes.
P0304 - Cylinder 4 Misfire
P0305 - Cylinder 5 Misfire
P0306 - Cylinder 6 Misfire
P0300 - Random / Multiple Misfires
P219B - Bank 2 Air/Fuel Ratio Imbalance
P2098 - Post Catalyst Fuel Trim System Too Lean Bank 2
P0175 - System Too Rich Bank 2
P0430 - Catalyst System Efficiency Below Threshold Bank 2

When I ran codes, i found the Freeze Frame Data
with the following information



As you can see the Fuel Trims are VERY Rich. My B2S1 (Wideband) was reading Lean in the range of 1.3-1.7 Lambda and the B2S2 (Narrowband) Was at 0V. I check this Sensor and found that it was dead. I bought a replacement for the O2 downstream (B2S2) and now it is reading 0.98v so Full on RICH.

I gave the engine a Vacuum leak and then introduced brakeleen into the intake and verified it was reporting correctly. The Upstream on Both were responding to Lean and Rich but I found what i think is an issue. The Bank 1 Upstream is fairly flat line and responded accordingly but the Bank 2 Upstream is very erratic and didnt follow the Bank 1 very well.
Note that the Bank 1 was going into Closed Loop but then would Open Loop (due to Fault) and Bank 2 has always stated Not Reported which makes sense with the fuel trims and erratic reading from B2S1 and B2S2 reading Full Rich. Also note that the upstream sensors were swapped from bank 1 to 2 and 2 to 1 for comparison and the erratic behavior stayed on Bank 2 which leads me to wiring or ECM issue possibly.  
See this video link for Graphing of sensors.
Video testing Both Sensor 1 on each bank

Also had the engine hit what i assume is Limp mode. The engine would rev up to 1500 rpm and the B2S1 would go FULL LEAN. After cycling the ignition it would go right back to what it was doing. Here is the Video of Going FULL LEAN

Performed a smoke test on the engine to see if i could find any vacuum leaks and found that the boot attached to the Throttle Body was leaking bad around the seal and the EGR body was also but as many of you confirmed that is normal. I have since fixed the Throttle Body leak with a new boot and passed the smoke test.

Also tested the Lambda readings with and without the MAF connected and got a strange result. Without it connected my Bank 2 Lambda was hovering around 0.8 and with it plugged in I was at Lambda 1.2-1.7

Things I have yet to check was the Timing (which would be done with PicoScope) and Fuel Rail / Injectors.

Curious if anyone has any ideas of what maybe causing this as I am currently lost on this one.

Any help would be greatly Appreciated!!!!!!!!

 

The freeze frame showed 0.73lbs/min 
I'm not familiar with that unit of measure for mass air flow, but Google conversion puts it equal to 5.5gps @ idle.
General rule of thumb is 1 gram per second per 1 litre of displacement, or about 3.5gps in the case of a 3.5l V6
