Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

There are quite a few things that can cause misfiring and it's going to require some diagnostics to determine exactly what is going on. Misfires are very often caused by ignition issues but it could also be a fuel delivery or quality issue, inaccurate sensors, injectors, even an internal engine issue.

Has anything been done to try to diagnose it?

I replaced the plugs about 6 months ago. Everything has been fine. While passing on the interstate under hard acceleration the check engine light came in and “reduced performance” appeared on the dash. I hooked up the scanner and pulled the codes I sent you. Also, I doubt it is bad fuel as I filled up the day before and had driven about 100 miles with no issue and it seems to be an issue with the cylinders on the right side as you face the truck. I am also wondering if it could be a a cam shaft sensor or could have jumped timing.

Do you feel it running very poorly?

Is there any abnormal engine noise?

Rough idle. The ECU has it in what I would call limp mode.
