Found a great video on doing this job. Not obvious for the first timer like me since I haven't done this on this car yet, but once you've seen it, you wonder how you didn't figure it out sooner. My issue was #5 is pulling timing about 10 degrees compared to the other 5 under hard acceleration, with or without a tune, its just more obvious with the tune. I'm replacing plugs since it has 83K miles and who knows if these are original., and swapping coil packs with #1 to see if it clears up or moves to #1, once the snow melts since #1 is super easy to get to if it is the coil pack..
