General Misfire Code
Hello everyone
Just wondering I have 2011 with 3.5 EcoBoost and kept getting a general misfire code and I already replaced #6 ignition coil and plugs and still getting the same code so I bought the other 5 coils and before I can replace the I get a faulty 02 sensor code. Just wondering if its actually the 02 sensor and not the coils. Any help is appreciated

You are very vague about your issue but I will take a stab. Which code are you getting?Why did you pick # 6? A fuel pressure problem can cause a misfire.An injector can set up a misfire too. I believe you are getting the O2 sensor code as a symptom of the misfire. I would address the misfire.
