My #3 injector tested out of spec. The normal resistance should be 10-14 ohms. All of my injectors tested at roughly 10.4 ohms. And my #3 tested at 18 ohms.

Is this terribly bad? I know it's only going to get worse. My car is running pretty good right now.

Should I wait until it causes some popping noises or should I go ahead and replace it now?

How hard is it?

And what parts should I replace while I'm into my motor? KS, VTC, injector o-rings?

So, who has tested the resistance of all the injectors? What did you find? Thanks.

 

not quite ot, but I have the same questions regarding a VG.

 

only prob ive heard on injectors is gettin it outa da fuel rail, that and making sure all the new o-rings are in place properly...check w/ jeff92se, he had sum injectors 4 sale...

other stuff to check while youre dere...valve cover gaskets, knock sensor, eric talked good stuff about the injector tuneup kit dealie...$60 bucks and prolly worth it...are your vtcs bad?

gaskets r a pain on dat 1...i think the lower intake gasket is like $50 bucks...ouch, i have an upper intake gasket if u want it, when i did my rear valve cover the thing still looked good so i just sealed it up and it didnt leak...good stuff

 

Thanks for the reply. I think whenever I go into my motor, I will replace KS and harness, do a VTC rebuild, and check all my injectors. It will need to be done one day, but for right now, I will keep driving it until I can actually tell there's an injector problem.

 

i have 3 injectors that read out of spec but my max runs awsome to, the front middle reads 18 and 2 on the back read 23 the rest all read 12 so im pretty much planning the same thing this summer but i am going to replace all 6 injectors at once plus ks and probly vtcs

 

Oh ok, so I guess that an injector has to be WAY out of spec before it starts causes problems.

Anybody else tested their injector's resistance? Results? Thanks.
