cylinder 6, and Dayton Ohio

So at 4:00 pm Fri, I decide” I’m going” to the ABA race in Dayton Ohio. Well that sounds good, but the check engine light is coming on and stating to flash, meaning a missfire!!!! So I decide to continue on, as I do the light stops flashing, but is still on. Now I’m not sure if it has cleared and the light is still on!!!!! Well at 277 milepost on 80 in PA, I abort!!!!! Today after going to my Bro’s and using his scanner, the light is on cause it was tripped, the module in cylinder 6 must have had moisture. I hate cars, should have loaded up the horse!!!! So much for a road trip
