Picked up off Craigslist, was running fine, did a coolant and heater core flush, turned it on, let it run for like 15mins, shut the hood and it bogged down and hasn't started back up since. This video is showing the results of my compression test (all good) and my spark test (all good) as I go through the process of figuring this out. I'm convinced I just knocked some strange and powerful sensor a loose. Maybe my process can help someone else.
