If you are OBDII then you have a DPEF sensor and they go bad and do exactly what you are describing. I have also had a lot of mod motors and the cop/spark plug miss tends to appear around 2000-3000 rpm at light load. (Mostly in third gear)

The lighter miss off idle has always indicated a DEPF failure in my experience with three different mod motors.

Good luck.
