Rough idle

I have a 2020 Off-road 2wd. I was on vacation recently in northern Georgia through the mountains. When we got back home to Florida today, I noticed it was idling rough. Driving at highway speeds, the truck had low power. I plugged in my obd reader and car scanner pro app. The obd-2 said no dtc’s were found, great news, but the ecu 2, 100 dtc’s were found. I find this hard to believe but I guess it’s possible. Anyone have any issues like this?

 

I guess I read the scanner pro app wrong. The truck didn’t throw any codes whatsoever

 

Is it possible you got some 'bad' gas during your trip?

 

The easiest first step is to clean your mass airflow sensor (MAF). Unplug your battery before doing this, make sure to use MAF cleaner (no substitutes), then, after reconnecting the battery, expect the ECU to take a few minutes to determine what the correct idle is.

How long has it been since the plugs were changed?

 

COPs jumping ?
happened to me once in a rainstorm, I had to stumble 200miles to home

 

I don't suppose you got some 85 octane up in the mountains did you? If so that can cause issues once you get back down low.

 

Thanks for the response everyone. After driving it around more, it feels like it’s stuck in s6, in the manual mode. I was shifting through the mountains to increase speed going up. Just don’t know how it got stuck in s6, if that’s what happened
