I ended up sticking to a .052 gap and no change. However it finally threw a code at idle... code 66 MAF voltage below 0.4. So I'm going to order a new MAF. When car idles warm I register 0.54 after it bogs I pull over and measure 0.33. WOT on bog condition is 3.55.

Also I know it's not a spark or ignition issue, plugs are golden brown so its stoich running perfect fuel, and when it goes this big condition, I leave the car in 2nd gear, shut it off, turn ignition back on and it'll pull hard again. So it's an electronic issue. I think now the MAF is my trigger after all.
