Misfire code using Sea Foam Spray [SOLVED]

After using Sea Foam Spray the engine fault code displays p1337 (combustion misfire). Is Sea Foam entering the engine too fast?

Thanks for the question, Song. It is not uncommon for Sea Foam Spray to cause a misfire code because you’re not burning a normal fuel to air mixture during application. Expect the code to resolve within 20 minutes of driving after the product application.
