You might want to fix code 85. It’s pretty easy to do assuming everything is hooked up. Mostly likely a failed purge vent solenoid.

EGR...I wounldnt worry

The sensor on top of the t5 can’t be fixed with trans in place. Need to drop or at least tilt the trans down. If your idle isn’t hanging I wouldn’t lose sleep but if you ever pull the trans I would fix it. Either add the pin if missing, or replace the sensor.
