Coils/spark plugs
I had a misfire on 1 cylinder and 3. I changed the gasket and all spark plugs .I have a code P2271 currently.
I started my car and I was getting a misfire on cylinder 1 now. So I tried switching it up. I put cylinder one to cylinder 5. That fixed the problem for like a day. Then I was heading to work then it gave me another misfire P0301 which is still cylinder 1. Would it be all coils that I need to replace now or what else could it be? |

How many miles? Are you running a catch can? If not, you may need to do an upper induction cleaning on it.

Could also be an injector.

Did you change the wires, particularly when you swapped the coils. The odds on all the coils going out at once are slim.
