bad injector?

i seam to have a miss fire that i notice around 2000 rpm. i dont notice it so much at idle only when it rev and hold it at about 2000 rpm with the engine out of gear. i think i have narrowed it down to the #8 injector.
i know i have voltage to it because i can swap it with the #6 injector and it will work. i have checked ohms at it i have 14.2 and if i put 12 volts to the injector it will click so it seams like it shoud work. why i think it is the #8 is when i rev the motor and hold it at 2 grand and unplug it the miss does not change. i pulled the plug and it looks about the same as the rest they all look like i am running a little rich so what gives could my injector still be bad? they only got about 3000 miles on them and there only 1 1/2 years old. o yeah they are venoms 24/lb p.s i did check a diffrent plug wire and i had 13.000 ohms on the #2 wire that sounds a little high to me
