2017 Ram 3.6 Misfire issues

[Boony]

My Ram started to run very rough the other day but never showed a check engine light. I hooked my scanner up and it showed 6 codes. 3 for P0306, 2 for P0300 and 1 for P0303.

I changed the coil and plugs for the 3 and 6 cylinder. It still shows the same codes as permanent but still has not turned on the check engine light.

The little Eco icon comes on and off and dings every now and then. Any help or info is appreciated.
