The timing part of it looks just like spark smoothing. I have to believe you when you say you turned it off and it made no difference. That combined with what I know you've done over the past few weeks and I know it has to be something you've done.
If you brought the car to me to fix this one problem, we'd wipe it clean and start over with just the basics. Probably wouldn't touch half the tables you have, and we wouldn't have any funkiness.
It really is about the importance of fundamentals. You start with the basics/fundamentals. you get them solid, ironed out. Then you make small adjustments elsewhere WHEN REQUIRED not because someone said so on the innerwebz.
When you end up with problems like this you don't continue to add or change things to fix it, you UNDO what you've already done and either start over or work your way backward.
