Crazy engine vibration

[SVX10]

So, I just completed the 5MT swap and now I have a horrific engine vibration .

I understand the importance of driveline angles, U-joints, and CV joints on the smoothness of the vehicle while driving. HOWEVER, I know that my problem is related to none of the above because it occurs at a stop in Neutral, when none of these components are moving. It also occurs while driving. I cannot troubleshoot any driveline vibrations until I get the engine vibration tamed. Here are the symptoms:

1. Engine codes read 24 (bypass valve), and 19 (fuel injector #6)
2. Even after clearing codes, 19 and 24 are still there
3. At a stop, in gear with clutch disengaged there is a strong vibration that increases intensity with RPM. If I put the car into neutral and engage the clutch at idle, the vibration changes slightly, but is still noticeable. Keep in mind that when I say idle, I mean 2000RPM because I'm having issues with the bypass valve and the 5MT as many members do after the swap

I will check injector #6 by unplugging it and seeing if the problem goes away. Which of the 2 rears is #6? Driver's side? During the 5MT swap, I disconnected a bunch of stuff (of course), but didn't touch the injector connectors. Is there anything that gets disconnected that could make the #6 injector act up?

Any other ideas as to what it may be? Thanks in advance !
