The codes only you give you a starting point by identifying the circuits that are giving "out of spec" readings. You really need a service manual with the diagnostic tree for the error codes. That said, I would give the mass air flow system a through cleaning with something like injector cleaner or brake cleaner. You want to remove any buildup of carbon. Check all of the air or vacuum hoses and make sure that they are connected and don't have any cracks.
