    jeep cherokee 6.1 cruise control WOt issue

    Hi i have another custumer with a 6.1 supercharged + 450 walbro + 800 FID injector . The problem with this truck is when i use the cruise control on the highway above 80MPH or so the truck goes in Open Loop in m log , the AFR goes in the 12,8-13 an stay there is does not come out of the open loop until i hit the brake pedal. I realy don't know what is causing that.

    Thank you for the help

    FWIW, there is a cruise control recall on a bunch of Mopars. I don't know exactly what the issue was though.

    Not on the 6.1 though, only effects those with the auto-cruise control, which i don't think the WK1 ever had.

    Confirmed MY 2014-2018 Jeep Grand Cherokee.
