If you don’t have access to a smoke machine, you can use something as thin as a coke
can, cut a piece, and make a temp “block off plate between the EGR and the intake. If it doesn’t do it again, found that problem! As for the tps, did you have the battery disconnected while redoing the computer?
That replacement cap area looks suspect. I would ohm it to make sure it’s good. Inspect the entire board!

Ohms test can show you if a trace is broken. The guy that rebuilt mine showed me all the different ones that were broken.
If for some reason solder wasn’t making the connection, it would show if you tested before and after the solders.
