LB7: Replace 1 Injector or All 8???

[jonathancasey19]

Injectors were replaced approx 50k miles ago under extended warranty. Injector #2's rates are out of spec. Thought of just replacing one injector since others look okay. Is that a safe idea? I've spoken with a few people, one included who did the same thing then ended up with 3 cracked injectors and 2 BENT???? Ended up having to replace all 8 said if you do one do them all at once. Kinda don't have the $$$ right this second. Opinions?

Injectors can be trickey, They will compensate for each other. You might be able to get away with changing just one, but it might just throw a different Balance Rate out of wack. That said I would try replacing the problem injector first and then go from there. What was the B/R??

tough spot i know! i think we've all been here! as easy as it may seem i would replace all eight, or at least the four on the same side. i have learned alot of lessons here lately!

3.8 is within spec, not by much though, id leave it be...

I will leave it for now but Iam just wondering what is best to replace just the one or all 8 the others are close only # 2 is -2.2 and #8 is +3.8 and it is just getting a LOT louder again

I'll check the balance rates again in the morning and let you know. Decided to replace all 8. Have to wait to get a break from school....

I wouldn't risk it personally. I would do all 8. It would be different if the LB7's injectors had a good reputation.
