So I took out the fuse for OBD2 checked it and reinstalled. It gave me an error once more but then worked. I noticed while it was communicating I heard a strange noise. The video above explains the noise.
This is the same style noise I have heard once it dies and I pop the hood.

The video says the engine is running. It could be an exhaust leak at one of the crossover flanges.
The second video could be a bad TPS because of how it only does it when you blip the throttle. The TPS sensor sets up the entire spark and fuel mapping. If it’s bad the ECU is getting bogus load demand info and has to rely on the O2 sensor to correct. A bad TPS can cause stalling too. I’ve done quick IAC cleaning by removing the lower idle bypass air tube and spraying in the hole until clean chunk free TB cleaner is visible coming out the air port in the throttle body throat.
Get a scanner that reads live data. I have a hand held Innova and a Mac Mentor. My Innova is my main go to scanner.
Dash Command is on my iPhone and torque pro is on my cheep tablet.
