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 will throw all three codes at once typically at highway speeds. Intercooler has been drilled at the bottom. Looking for suggestions, and any help is much appreciated.
