2014 3.7 V6 Misfire
I have a 2014 Mustang with the 3.7L V6. At around 70K miles I was driving in the select shift mode, and using it very tame, not really going above 3200 RPM, when it started misfiring. I turned the car off then back on and it went away. That was about 2.5 year ago, and every once in a while now, while driving under load, it will start to misfire again, and the same thing will happen, turn it off then back on and it is gone. This started only after a mechanic changed the transmission fluid. I have changed the sparkplugs and coil packs and it still happens. It has done it once every couple months and now has nearly 100K miles on it. I cannot seem to figure out why it keeps happening, does anyone have any ideas as to why? There are no vacuum leaks, and it is not the plugs or coil packs and I am out of ideas besides maybe going bad O2 sensors.
