Just got done doing the 703 injector swap in my 98 xj I Love it.. As for the results now much better throttle response feels great. I will let you all know what it does for my gas mileage. Anybody who has not done it yet I recommend it.

 

how hard was it? is there a how to guide?

 

Very intrested in a how to been at the jy and looked at neons but didnt know how much work was involved so i never pulled anything

 

There is a lot of good information available if you search for "injectors".

I have mine in hand, just waiting for rebuild kits.

 

Not hard at all. They are pretty straight forward basically.
-move around a few lines
-unbolt the fuel rail
-unbolt the bracket that holds throttle cables to get them out of the way
-unplug injectors make sure to either mark the plugs or put them in a spot to where you know where they belong
-pull the fuel rail from the intake (will take some persuasion)
-Take clips off injectors that hold them to fuel rail
- pull out injectors
-clean out the fuel rail holes with sand paper or wire brush, or else you will have a time getting the new orings in the holes and possibly break a few orings
-reverse this with your choice injector make sure to buy all new orings for injectors

 

There is my small how to in a nut shell.
