The P0171 combined with P0174 code, it's likely that the problem is caused by an intake leak. NO intake leaks, the next step is to check the air filter and clean the Mass air flow meter. If the issue remains HEGO (front) oxygen (O2) sensor(s) may need to be replaced.

Yes, those are classic codes for a vacuum leak. Check all your hoses and gaskets. You can have a smoke test performed to find it faster than a visual inspection.
