I know already its a short in my injector circuit. What I need to know is what causes this. I have had all of these fixed then boom all of them are back. Also what should the ohms be testing at? This has literally parked my truck for a month now and I'm lost for ideas on what it could be. I was told its under the valve cover but all of the injectors are torqued to spec. What else could it be. This issue is driving me insane
