Wondering how it turned out and any complications for you guys. I did it and i got 11mpg (normally 17) and a check engine light (yes i unplugged them all to make sure they were spraying and listened for a difference), but have now discovered that you need to reset the computer, which i did not do.
Anything else?
They are from an '04 DOCH 2.4L so pretty new and rust free.
Good o-rings...

The 704's are the wrong injectors. I'd return them and get the 703's as they're the proper ones you need.

CarolinaBoy

704's are for the renix right ?

nismo5

nope 703's for the renix

Mr.E

yea 703's are what you need. some one is selling them on here. and he cleans them up. i got a set off him but i have no idea if they were sent yet. reset your ecu drive a tank then seafoam. after i seafomed with stock injectors i was getting 15/18 mpg.

Did a complete top end rebuild, including 703's and a re-set (thanks cf, I would have never known....put your right foot in.....) couldn't be happier, looking at about 15-17 city. Don't know about 704's, but I got better response, smoother idle and better mileage.

703's in my 97 Ooppss, didn't mean to quotee

Sorry guys i dp have 703s, not 704s...i was too lazy to look in the garage but they ARE 703s....so my question now, who has done a succeddful 703 swap and how complications did you run into, what should i caution? this is my only car...

mrfajita

I swapped them into mine (also my only ride) and reset the ECU. Works great, better response and mileage. Only odd thing is an erratic idle in the first 15 seconds it runs if its cold (this morning it was below zero when I started it and it dipped to ~250rpm for a few seconds, then up to 1700, then back to 1000 like normal)
That is an extreme case, normally its a drop to 700, up to 1400, then 1000; if its warm it doesn't do it at all

red97cherokeewithsunroof

you have a 96 right? do we have the same engine? (mines 97)

mrfajita

Yep they didn't change the engine (whatever they did to it) until 98 or 99.

red97cherokeewithsunroof

the only thing that changed in 99 was the intake manifold got bigger, resulting in 10more horsepower. i bought one because theyre direct swap in but dont have time for the amount of work so i sold it
so how are mpgs before and after?
also
when i left off the brake and hit the gas at a normal start rate, i can feel the weight off the truck very well, how did that change for you from take off and acceleration?

mrfajita

Didn't change much for acceleration, but I can actually do the speed limit on the interstate now! Back in summer when I could get good fuel without ethanol, before the swap I got 17-ish, after I got 21 one time. Now I'm getting 16 due to crappy winter blend gas.

sweet man
thanks a lot

You shouldnt have been able to get 703's from a 2004. What code were you getting when the check engine light was on?
