Well, luck ran out. Got the AOS installed. Same symptoms persist. I can feel the crankcase getting ventilated, I removed the oil filler cap and could feel a slight vacuum. So I know I'm getting vacuum now. Here's a video of it running (if you call it that). I'm kind of running out of ideas. These are the same spark plugs that I have been using. They're getting spark but they were soaked in gasoline at one point. I may be down to injectors, but I'm having trouble believing that three are sticking on cylinders 4, 5, and 6.
