    Supercharged 06 Wrangler P0068

    Anyone come across this? turning the code off does nothing, Airflow max rpm or tps tables dont seem to affect it. According to the oem manual, trigger condition is supposed to be less than 1.59"hg above 2000 rpm with the throttle closed. I can make it happen at 22-24% throttle (closed is 15%) at 2200-2400rpm so basically just a light cruise at 30ish mph. though it'll hit anytime you're light throttle cruise. it turns closed loop off goes into pe it seems...super weird. No P0068 threshold table to mess with either.

    Heres a better log showing it driving along. I'm pretty sure the code hits when the ignition has a downward spike.
