P0174 is Bank 2 Lean.

Check intake air system for leaks, obstructions and damage.
Check air cleaner element, air cleaner housing for blockage.
Verify integrity of the PCV system.
Check fuel delivery system and filter for restriction.
Check for vacuum leaks.

Since the code is for bank two and not both banks, a vaccum leak in the intake manifold is suspect. Use some carburetor cleaner with the engine running. Spray it along the intake manifold to cylinder head mating surface. If the engine stumbles when you do this, then you have found the leak. Good luck.
