Shakey and cylinder two misfire

15' Town and country with 3.6l. I've replaced injectors, coil packs, plugs and both bank 2 O2 sensors. Still getting a cylinder 2 misfire code. The van accelerates good but idles a little rough. It shakes the worst when in gear and rolling without giving gas. Hoping it isn't burnt valves. Any ideas?

Was a compression test performed on cylinder#2 and adjacent cylinders? Removing #2 spark plug can give valuable info; unburned raw fuel, oil fouled, zero spark (spark test needed), etc.
