According to the helm, you can test the resistance of the injectors and should read between 10-13ohms. It says to warm the car up to operating temp and then do the test as well. Completely warm I am getting 17ohms on each injector with a small variance of about .5ohms. With the car 100% cool, I get 12.5ohms on each injector. With this in mind, should I replace these? Seems rather hard for me to believe that all 4 are dead. Has anyone else measured the resistance of thier injectors to see how they compare?
