ecoboost

Have a 2016 f150 2.7 ecoboost. Started throwing codes for multiple cylinder misfire, and cylinder 1 & 5 misfire. Have replaced all the plugs with mastercraft plugs gapped to 28, and replaced cylinder 1 & 5 coils, still throws codes. Has a slight idle shudder. Runs and cruises fine. But randomly...
