Your fuel injection enriches the mixture depending on the temperature and how long it takes for the engine to warm up. Carbureted equipped engines have either a manual or automatic choke which does the same thing. From looking at your avatar, you're located in Michigan and I'm guessing it's quite cold there like where I'm located. Continually running it cold with other issues may wash a cylinder down, trashing your engine. I'd get off the computer and call someone knowledgable who can make needied repairs.
