2008 Ulysses with 10,353 miles developed the hiccups and RPM surge and drop. Check Engine light came on and code referred to O2 sensor.
Over the past few months the following was replaced with no change: O2 sensor, Temp sensor, Intake seals, fuel pump, spark plugs and finally ECM with TPS reset. I have a coil and plug wires that have not been installed yet.
In the photo, there is a fitting with nothing connected. Anyone know what this does? Should I install a plug?
Thanks!
Unknown fitting under the air box

reset AFV to 100 start bike and allow to idle for 10 minutes to learn new idle curves. Go for a easy ride for about 15 20 miles and you should be good

Missing port was causing a vacuum leak making it appear as a seal leak.Port is not used for your bike.

Thanks GD.
I do not have any programming equipment, Is there a way to reset AFV manually?
