Car started to studder under full throttle on the way home from dinner tonight. Seems to be fine and idle perfectly when driving normally. I have been able to repeat it only under load/boost. If I put it under a heavy load in 3rd and 4th it will break up a bit. Popped the hood when I just got home and nothing looks amiss. Figured that I would let it cool off and check the plugs tomorrow (probably 15K miles on NJK's, since pulley/tune/intake upgrade). Nothing has changed with the car otherwise and everything else is working normally as its a daily driver and gets miles on the regular, no codes, no lights, but I can feel it. Had to do a few short lower 3-5K RPM pulls before the wife could feel the studder as well. I've got Lund tuner in the car and logged a few of the times that I duplicated the studder, once I get a few things done at home I'll pull/post the logs.
Anything that I should check first, am I wasting time checking the plugs?
What should the plugs be gapped at, might as well check that also.
