Getting Code P0174 Lean Bank 2 Only.
Cleaned MAF, replaced fuel and air filter, no vacuum leaks.
IDLE CONDITIONS scanner data:
STFT BANK 1 (-4.5 TO 3.1)
STFT BANK 2 (-3.9 TO 2.3)
LTFT BANK 1 ( STEADY AT 1.6)
LTFT BANK 2 ( STEADY AT 9.4)
O2 BANK 1 #1 (.1 TO.7)
O2 BANK 2 #1 (.1 TO.7)
O2 BANK 1 #2 (.7 TO.8)
O2 BANK 2 #2 (.7 TO, 8)

Upon starting from cold condition both LTFT were at 25, then settled to values above.

Any ideas on whats wrong or what to check?
