Multiple Misfires On Bank 2 Only

[69sixpackbee]

Greetings, I have a 2008 F150 with a 4.6, 4 valve engine, and I’m chasing multiple misfires on bank two only. I’ve swapped coils to no avail and I’ve done scans and road tests. I tried posting a screengrab but it is too large. I will take the numbers off of the test and tell me what y’all think. I’m leaning toward possibly an intake leak at the manifold because the rest of the numbers seem pretty good to me. There’s a large discrepancy in the short term fuel trims from one bank to the other. This just started recently and I thought it might’ve been plugs so I changed the plugs and to no avail. See what you guys think. Am I on the right course?. Thanks in advance.

When I did a mode six test, it came back with multiple misfires on cylinders 6,7 and 8

Check camshaft timing with the scanner. I prefer to pull the valve cover to check, but a scanner is faster. One chain may have jumped.
