The first wire I pulled was the one all the way to the back and between the motors. I worked from the hardest to easiest. That first wire, I pulled the cap and the metal tip stayed on the plug. After the 2 back ones it was easy. The problem was that it wasn't the problem. They needed to be changed anyway though. They looked crappy and like they were overgapped. All good, thanks though. I never had one of these messages before. It's never the first thing that I try when I'm fixing things. It's rare to hit it unless it comes up on the diagnostics.
