Maybe check your gaps, make sure they are tight. Is it throwing a code at all? Could be the coils. If it does throw a misfire code or something, flip around coils to see if it code follows to the new coil cylinder. If no then its in that first cylinder it said. Run techron concentrate every oilchange. Best additive for ecoboost injectors. Maybe you got a bad spark plug, quality control su cks as s these days. Even msd is one of the worst but so far no issues on my msd coils for over a year

They list 4 plugs for our application. SuperYttrium, Premium EVO, Silver Racing and Premium Racing. Which one did you choose and why? They all appear to be 15 heat range except the silver racing which uses 14. What range did you go with?

@Ecoboost_xsport thank you for the write up on your blog.

I installed the Silver Racing ones-RR14YS /.026 gap with MSD coils !! Didn't have any issues on idle before !

I have the same thing, but I used Motorcraft plugs and did the muffler delete. Afterwards fired it up and it surges from 600 to 1000 sitting and idling.

I gapped plugs at 30
