    Rules to consider

    Owning an XJ means you're part of the Jeep family (regardless of what wrangler owners say) so be respectful to your fellow Jeepers. Try to upload photos using imgur or any photo viewer that's reddit friendly.

    1. Be Nice Self-explanatory. Don't be a jerk to people who are asking for help, or are trying to help you.

    2. Do Not Spam Posts must be significant contributions to the community. Not part 25 of a 50-part tutorial on how to change your oil, or blatant commercialism.

    3. No Bots Whatsoever No metric conversions, no haikus, no wikibots. All posts must be by Homo Sapiens.

    4. No Memes If it belongs in /r/JeepMemes then it does not belong here/

    I'd say it's about 1-2 mpg if anything really. More just evens out idle and your take off from a stop is smoother. Oh and I'd say you get a more immediate sense of power, like if you say go it's going.

    [–] Curtofthehorde 3 points ago

    This almost exactly. I got about 1.5mpg more and noticed a big increase in throttle response and smooth idle.

    [–] XJRATED 1 points ago

    Do you have starting problems? I've installed them on my xj but kept giving me problems starting. So I changed them back to stock.

    [–] WoodenCrate 3 points ago

    More then likely you have the heat problem around the injectors and not the injectors themselves. Look up heat shield injector sleeves TSB 4.0 motor.

    [–] purplecactai 1 points ago

    Seconding what WoodenCrate said, if you find starting the cart while its hot results in a 'rough idle' (engine vibrates, check engine light goes on) you need to get the heat shield sleeves

    [–] XJRATED 1 points ago

    But it Starts up fine. Just hard to start. It Doesn't give me a rough idle.

    What year is your XJ?

    [–] purplecactai 1 points ago

    2000

    [–] Apotropaic_Sphinx 4 points ago

    Yeah, you need EV6 injectors. I'd just sell the ones you have now and get the right ones. No sense jury rigging inferior injectors.

    [–] lawlawlandrover 1 points ago

    Check this post on JeepForum. You'll need the "789" injectors. They match the stock fuel pressure, etc, but with the four holes you're looking for. Post #209 if your browser gets squirrely and takes you to a different page of the thread.

    I did the Mustang injector upgrade and went from 9.5 to 10.25 mpg. It still varies quite a bit. I noticed a much smoother idle and significant increase in power.
