Cleared all Faults, inspected all potential vacuum areas. Found a broken intake clamp. Replaced. Fixed the issue. Car purrs. Thanks for finally getting me to understand that codes have to be wiped out individually w/in modules

Last question, Oil inside coil pack tube and heavy, unburned on inside of plug. Thoughts of causes?

Bad seal at valve cover. Each spark plug hole has a seal around it where it passes thru valve cover. A valve cover gasket set would come with those seals.

Bad seal at valve cover. Each spark plug hole has a seal around it where it passes thru valve cover. A valve cover gasket set would come with those seals, and you have to pull valve cover to get to them--from the inside.
