I know that the injector plug and the coil plugs are good. I can switch them with other cylinders and they work just fine. So I think it must be the injector right? I check the injector with the ohm meter and it showed 12 ohms. So what else could it be? I know that the injector tested good but could it be a farther problem other than the fact that it test good that way.. ie: spray, or something else? HELP my car is almost running right... lol :) What did you mean by check grounds? like where?
