Resistance values on injectors doesnt matter as much as are they all about the same? Injector resistance will change with temp range. If you have 5 at 12ohms and 1 at 2ohms, you got a bad injector.
Another way to test them is listening for clicking noise at each injector with a stethoscope. Sounds crazy, but it works!
i did listen to them before testing them
with a screw driver
the only ones i could get to with the manifold on were #1and #6
both were clicking (or so i thought)
but when i removed the maniford to look at other injectors
and tested them 12 is what i got w/ the non-adjustable meter
then tried with a different fluke adjustable ohm meter
was better #6 shows 2.2 ohms but its clicking
that one must be realy broke
i hope
haven't done much testing of fuel injection
another on said 11.6 low side of being good

so i think im replacing them all
found a site were injectors are cheep
hopfully they are as good as they say they are

fixed it bad injector

thanks all
