Odd finding at vapor canister by spare tire

[Summers22]

So I have been getting this truck up to my standards with neglected maintenance items. Finally got all codes cleared, no misfires, monitored live data for 30 minutes at idle. Went for a 30 minute stop and go drive, monitored again, 100% good to go. Had lots of power, smooth idle, etc. Went to replace my rear shocks the next day and the lowest hose on the vapor canister that faces toward the frame by the spare, was not even hooked up. So naturally I put back in the hole, it snapped right in with no problem. Started the truck back up, rough idle AGAIN, drove it around the block and the thing is low on power. Does this mean the vapor canister is clogged? Why didn't it set off codes the day prior? Here are my EVAP numbers after it ran for an hour and was running flawless:

By looking at the EVAP system diagram, is it basically a hose from the gas tank to the vapor canister purge solenoid from the solenoid to the vapor "charcoal" canister, then a line up to the purge valve , then from there to the intake manifold? Guess I need to drive this more to hopefully get a code and know which of the parts needs replacing.
