Well, we swapped in a fresh set of plugs and it didn't seem to help...my thoughts were maybe the coil packs? But I'm assuming that if something was up with the coils we'd see that by the AFR fluctuating or misfiring throughout the powerband. I was also thinking that IF the coilpacks were going...maybe the problem only existed in certain parts of the RPM range.
