I would think the injectors are not the problem and none of the DTC's indicate a injector issue.
A vacuum issue would cause high erratic idle so I wouldn't think that vacuum is the problem but check it anyways also check the vacuum stem and make sure the rubber plug is on and in good shape.
I would suggest replacing the Engine Temp Sensor which is DTC P0118 and inspecting the wiring, the ET sensor is located in the left rear of the front cylinder head just behind the horn.
The engine temp sensor affects idle and AFR and it will cause all sorts of running issues, and it is a easy fix.
After you replace the ET sensor make sure to clear all the DTC's before starting the bike.
This isn't a TCA issue but it doesn't hurt to put some dielectric grease on the TCA plug located at the rear of the throttle body.
