94 YJ will use the same injectors as the 87-98 XJs - the *703 injectors

I did mine last weekend. It was pretty simple and I have noticed a huge difference with it. At idle, acceleration as well as gas mileage. In the past few weeks my mileage dropped from a leaky (#6) injector. Mine is a 98 and we had clips, I left the fuel rail attached at the hard lines and flipped it around to be able to remove each injector. To remove the injectors and the rail, I found it easiest to stand on the drivers side and pull evenly until each one 'popped' out.

I did mine a couple weeks ago using injectors from a Jeep Liberty 3.7liter V6. I have a 1990 XJ. I used this thread to inspire me to do the job as I have never worked on the fuel rail before. I also did a YouTube video to accompany this thread. http://www.youtube.com/watch?v=Izj6q6o59L4

After everything was all said and done, I would add an asterisk on step #6, disconnecting the fuel lines. In my FSM it states that whenever the fuel line is disconnected, the o-rings should be replaced. I would recommend you have the o-rings on hand PRIOR to starting the job. I had a thread going over here with details on the o-rings;

My '01 4.0L Grand has been generating cylinder misfire reports for the last year. We've swapped the coil pack, but I've been thinking that it may be bad o-rings on my injectors.

Would cracked rings generate misfire codes?

Thanks.

bad orings are most likely not the cause of your misfire code.

clogged injectors however might be. It'd be worth taking them out and soaking them in seafoam overnight and clean them up, then re-installing them with new orings.
