Default injector test

Can anyone please tell me how to test my injectors? I had a service manual that had outlined this procedure, but have since misplaced it. Thanks :cheers:

On or off the car?

One method is to remove the fuel rail and place a jar under each injector. Crank the motor several times and see if you have about the same amount of gas in each jar.

You can also check the resistance of each injector with an ohm meter. I think you want them to be within 1 ohm of each other.

The injectors are currently installed on the car, however I'm having some tuning problems so I am going through the process of elimination. :cheers:
