Thanks- I’ll submit photos tomorrow- changed plugs- wires-Dist cap- erg valve- o2 sensor- thermostat although engine is not running at same temperature level- engine coil pack- and other items. I’m thinking the thermostat and o2 sensor are sending back signal??

Plugs fouling plugs- 2 on each bank- have tried many things at this point? Any ideas ?
