Ok i have two injectors that seem to be out #8 and #5 my #8 went out first the balance rate was -4.25 when i first checked it and all the other ones were between .01 and .80 and now i checked them again here a month later and #8 is at -5.25 and #5 is at +4.75 and the others all went up to between -.03 and -.90, so i asked around about this problem thinking that i have to replace two injectors but i was told that if number 8 goes out first that it will through all the balance rates off of the remaining injectors showing they are out of spec but are really not so i want to know if this is true or not and can i just replace the one, i cant afford to do all 8 of them at the time. So can someone explain to me how this works if true, oh and these are my second set with 60,000 on them. thanks

sorry man i can't help your actual question, but i do know that if you only replace one, it will show the rest compared to the one new one and show that the rest are bad. i would do all 8. i am in the same boat except that mine arenot as bad... (my worse 2 are at -3) but i am waiting till i can afford to do all 8 becausei dont want go be in there twice.
