If you get these codes check the following :
1. Make sure clamps are tight on air intake hoses.
2. Make sure air intake hose and other rubber hoses have no visible cracks.
3. You can test for vacuum leaks that set these codes by using a unlit propane torch turned on, or starter fluid. Start engine and spray starter fluid or wave the propane torch around the hoses, pcv valve, intake etc. If the vehicle idle speed changes you found a leak. This could be in a vacuum hose, intake gasket etc....
4. If you find no leak it could be a dirty Mass Air Flow sensor or a defective one.
