Just an update. Removed the primary fuel bowl and metering block las night for cleaning. Used carb cleaner and thorowly cleaned every passage. Removed idle air screws and cleaned those as well. Put back together and my idle is back to perfect. Cruise no longer has a light throttle stumble. The only lean surge left is light throttle roll from a stop sign. Doesn't stumble but you can see it go a little lean by the AFR gauge. Maybe this will cure itself with more driving. Overall back to normal. Thanks FABO!
