You may have to disconnect and clean the battery and connections, then reconnect and drive it some to reset any code. if it resets the same code, you need to read and perform the tests indicated by the code. It can be injector on time is at stake, or injector issues. there is too much fuel present after combustion i expect. If you are behind on maintenance, this is a good time to find out and get that done with trying to get the codes to clear.
