So I have had a bad injector in my truck for awhile that has been sticking open. I ran some b12 chemtool through the tank in hopes of cleaning it before replacing it. Instead it did the thing in and now I'm running on 3 cylinders. I don't have a cat so I'm not worried about the extra gas but I can't get it changed for a day or two. Should I pull the plug and try to disable that injector or just leave it since it is still running until I can fix it. It's a 98 s10 2.2 4cylinder. No idea on miles on the engine as all I know it's not original.
