Check Engine Light after giving it on the highway

Hello guy's I hope someone can help me out with this... Twice after driving down the Highway and passing cars "safely" Just punching it to WOT, I get a check engine light, I've plugged my diablo trinity tuner and it reads P2097 Post Catalyst Fuel Trim System too Rich bank 1.

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...

I don't hear anything out of the ordinary.. Now that I have erased the code I'll have to punish my jeep till I get it again. That's for the feedback I'll get the garage to check it out and have it serviced.

Stick your head down just under the edge...
It is new, so I'd be more likely to guess either just a bad sensor [it happens] or someone crimped something when building.
