Bought a used 2015 Expedition. Had check engine light for cylinder #4 misfire. Changed out the coil and it was still tripping so I did the spark plug and now much better full throttle response. However, now tripping a cylinder #2 misfire.
Looks like someone already replaced the coil with an Autozone Duralast. Was going to check the plug, but the bolt that holds the coil in place just spins. Guessing they over torqued it. Looking for suggestions on how to get the coil out.
Hoping I can make it home as-is to Utah from Tennessee and then change all the coils and plugs. Drives great if I'm not on full throttle boost.
Attached a photo of the spark plug from #4.
