My truck started missing around a month ago it would come and go, i changed all spark plugs and tested Coils and reset ecu via battery disconnect. But lately it has gotten worse and the CEL is showing Bank 2 to lean. Below are data log pulls with info that could be helpful.

Did you do a compression test?

Was there any coolant in the well with the plug? Common for intakes failing causing missfires
