    Cool 99-04 Jeep Grand Cherokee

    Hello all!

    I'm looking to see if anyone has put an HHO generator on one of these vehicles. I have a 2000 Jeep Grand Cherokee Limited 4.7L V8.
    Give a man a match, and he’ll be warm for a minute, but set him on fire, and he’ll be warm for the rest of his life.

    15%-20% MPG increase at 1.5 Amps

    No gains.

    I have a 2004 Jeep Grand Cherokee. I have no O2 or EFI sensor fixes on it. I went from 16mpg to 24mpg using a modified Powertube-style kit as seen on YouTube. There's a box over the fuel injector, and that's where I've drilled a hole and stuffed that HHO gas in. I'm wondering if I should be messing with my sensors or would that cause other problems?

    Well to go from 16 to 24, I'd say you've pretty much nailed it! Congrats! Would you be willing to post the details of your generator?

    Which engine do you have in your 04?

    2005 Grand Cherokee Hemi

    I'm having no luck with my Jeep with the hemi.
    Feeding 2.3 lpm into the throttle body...no change in mileage.
    Anybody's advice is welcome...

    Average 15 mpg city, 19 mpg highway - plenty of room for improvement.

    Did your mpg go down after HHO or stay the same?

    It actually went down a little. With MAP and EFIE I could get it back up to original mileage. If I tried to get further gains with MAP and EFIE my engine light would come on.

    You have got to use a device to adjust the O2 sensor. mine wouldn't go until i got one.

    And what model of Cherokee do you have, and what is your current gas mileage with your new setup?

    2.3 LPM?? That is a lot of HHO! Have you tried starting with lower amounts and adjusting upwards?
