2007 GT Misfire

Hello,

I have an 07 GT Mustang and I keep having a spark plug misfire. I have had to replace the spark plugs 4 times in the 2 years I have had it and I don't know whats causing it or what I should. Any advice?

What OBDII code(s) specifically are you getting that indicate a misfire?

I'd look at the Coil-on-plug packs as the first culprit. if you know which cylinder is misfiring, swap the COP with another cylinder and see if the symptom follows the COP.
