2003 Mustang GT Problem!!!
#13
I had a misfire on mine, no CEL came on or any codes showed. It was only noticeable at idle and the #1 plug kept fouling. I took a chance and bought one COP coil (Borg Warner brand) and that solved my problem.
I guess you only get a code/CEL if you have a more serious or constant misfire.

I had the same problem and on myn what was happening is that the spring that connects the plug inside the rubber boot was coming off and it wasnt making good connection so i pulled the spring stretched it a little and havnt had problem since
