What is the correct impedance of the injectors on a 1989 formula 350 TPI?

GM service manual is hiding it from me, and Haynes says 11-14ohm

I have 4 between 18.0 and 18.2 the others are 6.8,9.6,6.7,and 14.8

Car is running like A$$, eratic idle, crappy performance when warm and PI$$ING ME OFF BADLY!!!!

 

i think i recall that anything below 12 is to be considered bad. i think mine are around 17-18. been a while since i messed with that. i know there are some posts on here somewhere about the resistance tolerance.

Yep, they are bad. Typical Multec failure. Toss them in the trash and put in a set of Bosch. Can get the SVO F*rd/Bosch injectors at a decent price.

Like Rbob said.

Trash them and go SVO.

Anything below 12 is garbage per GM manual.

If u replace the 3-4 bad ones the other 3-4 will fail and come back to huant you.

Thank you all. I was pretty sure thats the problem but it is always good to hear from others!!

BTW my name is Don and I live in Upstate NY WHAT UP EVERYONE??!!

 

hey if u want some injectors, im selling some ford svo's 30# injectors.
https://www.thirdgen.org/forums/engi...injectors.html

they all register 16.xx ohms.

 

Too big but thank you for the offer. I am looking at keepin the car close to stock so the biggest I am interested in is 24#. Thanks again though.

 

Looking for 19#?
I have a set of the Ford ones
I am running 26# so I probably won't use them?
Let me know?

 

Sorry again, I should have said it right out when TraviZ asked I would need 22#'s if I were buying them. I am watching on ebay at the moment to try and win some used SVO's

Thanks sophinity and I am sorry I didnt specify

 

with used injectors make sure they back them up that the impedence is good or u will have the same problem.

 

Yes I will dont worry. I do NOT want this same problem again!!!!
