LB7: injector balance

[sjgw29]

I have a 02 gmc with 150k on it. I ran a injector balance test with my cts monitor and warmed up in park all of my injectors are between 4 and -4 except number three. It's always around 5.2-6.3. Does this mean it's getting ready to go out? Or? Thanks in advance. Scott

could be, how many miles on that set of injectors? Really the only sure test would be a return rate test but that would require a dealer.

Are you having symptoms? Rough idle? Smoke at idle?

No issues yet. But I don't want it to leave me stranded. As far as I know this are the original injectors. I bought the truck with 130k on it.
