Few Questions after running AE

So I got my AutoEnginuity today and ran a few test on the 06 6.0. I was pretty sure I had a bad injector as it was running a little rough and some bucking when trying to accelerate while rolling, as well as low on power. After running a power balance it shows all cylinders are balanced. It is/was way to windy to hear the buzz tes,t so i'll have to do that later. I really didn't show any codes, besides P2285, which is due to a HPO leak and a warm engine. I know I have a HPO leak that I am pretty sure is a injector o-ring.

Now for the confusing part. When I looked at the onboard test results it shows a misfire. At first it showed it on all cylinders, then just cylinder 1, then just 2, then none, then all again. I got those different results by refreshing it.

I am new to AE and really need to figure out what is going on with my truck.

I am at a lose right now.

Since they are comeing and going I woud suspect a wireing issue from the FICM. Chafes or a loose plug. While engine is running jiggle the wireing harness from the FICM if the engine changes up how it runs thats yer problem.

I seem to run rough all the time. I was surprised nothing showed up on the balance test. It runs like there is a slight miss. I know it isn't a complete miss because I isolated each injector and you could tell when they cut out and back in.

So which one of the plugs on the FICM is the output to the injectors?

Okay So I took my FICM out and made sure the connectors were good and connected well, they appeared to be.

So I did a little data logging on a short drive. Ran like sh!& the whole time. Anyway the desired and the actual ICP are way off anything above 1200psi and they are no were close. I am pretty sure I have an injector to oil rail leak on the passenger side, or maybe 2 for all I know, I am wondering if that is the reason I see such a difference? Also would this cause the bucking and jerking when trying to accelerate, the low ICP?

Here is the power balance
