Hi, I have a 2012 honda civic that is acting up and was hoping someone here could help me before I go and bring it to the shop. It was idling rough on starting and then all these codes came up, got a reader and said that the number 2 cylinder was miss firing, replaced all 4 plugs and all 4 ignition coils with OEM parts and I`m still having the same problem with all the lights on the dash, check engine light, power steering light and emissions light. My code reader is saying that it`s my number 3 cylinder miss firing but how can that be when I replaced everything. Does anyone else ever run into this problem? if so what did you do to fix it?
