Hey I’m new here and need some help. Not sure if this is the right place to post this but I’ve been having some trouble with my 2008 si sedan. I recently got a retune and everything was going fine and about 3 weeks later I got an engine code. I pulled the code using hondata and it said all 4 cylinders were misfiring and also a random misfire. I’ve replaced spark plugs and I’m about to replace the coil pack. I notice a very small misfire only during idle and the code comes and goes like every other week. Any help would be appreciated.
