You might end up having to smoke test the intake system if you can't find any obvious leak(s). If you cleared it and its still coming back as pending then there's probably another leak. Have you sprayed starter fluid or carb cleaner on suspect hoses to help show vacuum leaks? P0174 is Bank 2 ( driver's side ). So give a good look around there and the intake gasket area on that side.
