I've confirmed all the vacuum lines are plugged in multiple times and I'm sure of that. However, even though I labeled everything, I have questioned if I accidentally hooked a hose up wrong. I feel like they only way I can confirm this is by having someone with the same vehicle come by to compare. I haven't found any diagrams that have been very helpful.
I appreciate your input

And OBD-II reader that does live data should be able to read the ECU's version of the O2 reading for the main and sub O2 sensors. That will be a start. You may still need to break out the multimeter to be 100% sure.
The sticker on the hood should cover *most* of the vacuum lines, though not all...
