This plot thickened a bit, plugs all changed with the NGK Rutheniums and timing belt kit done by Honda buddy. He said something didn't feel quite right after doing the timing kit and he pulled out his scan tool...
After some worry that the new plugs were fakes or the timing job wasn't done properly, turns out this is pretty common on 2017 Pilot's and it's actually failing fuel injectors that Honda has acknowledged and offered extended warranty (150K miles or 10 years).
