Will clean the MAF sensor ASAP.

O2 sensor signals seem to be fine. I'll take a drive in the next week and have my son capture the data at different loads and see where that takes us.

Thanks for the response!

Keep us posted let me know the results of cleaning the MAF.
watch Scanner Danners video on how he uses fuel trim waveform and O2 Signal waveform to detect vacuum leaks.
Dirty MAF or vacuum leak is where I would look first as to the cause of your hunting idle.
Have you had a check engine light come on??
