Would someone know what that means and why i'm getting this. The only modifications I have on my jeep is a catch can.
Like I said i'm getting this while I punch the gas to WOT a few times during my travel on the highway.
I run 91 Oct fuel.
BTW the car starter will not let your jeep run if you have a Check Engine light on. It starts but will shutoff after a few seconds
Allegedly that means you have bad wiring to an O2 sensor, a bad sensor, or a leak in the exhaust system. Its under warranty presumably and a decent dealer could isolate down by checking the voltages at the sensors.
Hear any funny spitting noises when on the gas? An exhaust leak big enough to trip an O2 sensor warning typically makes notable noise...
