Inspected all hoses and connections related to oil change and windshield repair. No fault found. Removed air cleaner housing to inspect throttle body and plate. Found excessively "coked". Cleaned throttle body and MAF sensor. Started engine to clear throttle body cleaner, then cleared codes. Shop suspects when air filter was inspected a small particle was dropped into the housing and drawn into the MAF sensor once engine load (venturi vacuum) increased, blocking the MAF sensor signal.
