62615, Injector problems and a small ? about bigger 450cc's need help ASAP
Posted by momo_jey, Nov-04-03 07:40 PM
ok guys heres my prob....
my car idles at 1700 with a cel code of 25 (vacuum leak)
i pinpointed the leak to the #4 injector (uner throttle body) i sprayed carb cleaner there and saw that when i sprayed around the injector it would race. my ? is is that just an oring problem? or did i slide the injectors slightly out of place when reintalling the fuel rail?

Also....(?) i have a set of 4x 450cc injectors from a stock 2g turbo..can i use these injectors? ive done a toooon of research on this question. something abot a resistor pack for the injectors? due to difrent duty cycle and different ohms?

thanks guys ...please help me out ASAP.
just so u know with the bigger injectors i also have my AFC for tuning afterwards...
What would i need to do to use these injectors?

you would definately need a resister pack to run those 450cc's. unless you are handy at electronics, I wouldn't try to use those. if you were to buy a pack from someone, most likely it would cost you close to/or more than a set of high impedance injectors that would fit properly and plug-and-play.

if you insist on using them, I believe that there are some models of hondas that have a stock resister pack that can be adapted. you would have to do an internet search though because I can't remember the years or models.

Did you apply clean oil to the injector o-ring before installing them? If not, then you may have pinched the o-ring. Or, the o-ring was damaged at some point. Anyway, remove the injector and replace the o-ring. You should be able to buy them at the dealer.

If you tuightened down the fuel rail and the injetcior seated then the o-ring is bad.

I also don't see a reason to use or adapt other injectors for our car when they make ones designed to work with our car.

I just mean rub the O-ring with some fresh 10W-30. It helps the o-ring slide into place easily (they can catch and get pinched).
