Quick update for anyone interested
Looked into all the suggestions that I have received. Figured out that cyl #1 was firing inconsistently. Tore down from there to try and figure out why.
Finally found that moving the ignition coil/spark plug cap from cyl 1 to cyl 2 cause cyl 2 to go cold.
Have a new one on order, should be in later this week.
Not sure why it passed all diagnostic tests and never threw an error code? Hoping someone may have an answer for that.
Either way, a relatively easy fix.
Thanks for all of the info and ideas. Checked into each one and got to the answer eventually.
