My car has a really bad misfire. The OBD has showed several codes and I have replaced every code that it showed.
I replaced two oxygen sensors, map sensor and the throttle position sensor. After replacing every code that the OBD is showing it did not change the way the engine ran. The misfire all started when I was checking the fuse box for a blown fuse for a tail light. I started the vehicle up after that and it has misfired every since. Even after the misfire I still found no blown fuses.

check duct work going to engine form air cleaner for holes or being off. But misfires are best handled by a mechanic as it can be a basic engine problem, sensors or injectors. so rather than change out good parts have a mechanic do it that is your very cheapest option. he has to scan and read sensors to see if they are operating right. among other things.
