So I see that there are several threads on this topic but not many solutions my truck runs smooth at all RPMs never feel anything off but the ses is flashing over 2000 RPMs changed the MAF off my other truck that doesn't have this problem no change checked intake gaskets no change while spraying intake gaskets open loop and closed loop no change in o2 readings. Any advice would be helpful. Attached is real time data from my scanner maybe it will help diagnose. Couldnt take a long video due to size restrictions on this site.

You need a better scan tool that can read individual cylinder misfires in real time. This way you can pinpoint what cylinders are showing the misfire. Could be a spark plug, plug wire, coil pack issue or injector.
