Thanks for the resolution. Most don't update their posts.

you need to run a reset procedure in ISTA-D to clear the ram in the DME that holds the calibration information on the solenoids. I ran into this same issue after replacing these today, after the reset procedure I could continue diagnosing the misfire. i will make a new post updating with the procedure instruction I believe these green orings are too large in diameter and I replaced them with some slightly thinner from a metric oring kit, and greased. Solenoids should always go in firmly but shouldn't need to be pressed with force that requires a lever or a mallet, that's just going to stretch and distort potentially destroy the soft oring.
TO the bro who installed the solenoid with a hockeystick, you know that's not coming out again without destroying it. I only did the left bank, but my coworker did the right bank. I'm still getting misfires on cylinder four but I haven't yet checked on the work. Maybe my timing chain is off slightly as well, so I have the alignment tool on order. The oring size I used on the solenoids; id 33mm thickness 3.5mm which was from the typical chinese universal oring kits. The oring is the right size to keep out oil drips but not encumber the installation process.
