I went out and took off the passenger injector shield, unplugged and removed the DI box and was just going to start from scratch.
First I noticed the bottom most plug on the DI was loose, still attached but loose. secondly I noticed the bottom most bolt was missing. So I put the shield back in, then I put the DI in but attached the bottom most bolt to the block to ground it, then reattached all the plugs firmly. Done! It works! Runs smooth and no CELs!
I believe the reason why it was working last night when I was idling but went out when I reversed out of the garage was due to either that plug vibrating loose or the ground vibrating off the bracket since it wasn't attached.

I did a quick lap around a few blocks and shut it on and off a few times wth no issues. I believe as of right now it's fixed!

Thanks a lot guys for pointing me in the direction of the DI!
