Took the air intake and a few vacuum hoses off to access the valve cover, painted valve cover and replaced gasket, replaced #2 hose with new from city racer, cleaned the engine bay carefully with dish soap and water making sure I hit no electronics, reassembled everything and now I have a rough idle. Sprayed starter fluid all over air intakes looking for vacuum leaks and no rpm changes. Seems to be fine at higher roms, plenty of power etc. See video below. Help!
