testing fuel injectors

is there any way to test fuel injectors on the car?

if i feel the injectors on my engine with it running 7 of them you can feel them ticking on the 8th one you don't feel anything. also if i unplug that injector it doesn't effect the operation of the engine.. any other injector it starts stumbling.. some worse than others.

i checked it with my ohm meter and it come up 13ohms.

i am guessing that its hosed?

Test any other injectors? 13 is close to the 12 ohms they are supposed to be. Have you checked for power on the pink wire to the injector? Have you used a noid light to see if the PCM is pulsing the injector?
