I’ve done a lot of research on this forum about this misfire code and I am trying to track down the fix for it. I changed my spark plugs and the light ended up coming back on the other day. Now I’m thinking I need to change my coil packs? I’ve also read it could be fuel filter or my cats are clogged? I will replacing my cats with tomei test pipes soon anyways so maybe that’ll fix this issue! But I don’t really want to buy 6 new coil packs and replace them if I don’t have to. They’re priced at $88 a piece at Z1. Can I test my coil packs somehow to see if I have a bad coil? And how can I access my fuel filter and replace that?
