Service engine light came on today. When I pulled the code I got:

DTC P0174 Fuel Trim System Lean Bank 2

Any thought on what could be causing this or what may need to be replaced.

Thanks DC!!

Lazy O/2 sensor.... Low fuel pressure..... plugged fuel filter.... Vacuum leak........... Faulty M.A.F sensor..... Do you run a K&N filter? If so your MAF sensor may be contaminated with oil residue......... Fuel injectors............ Just to name a few:rolling: No really, hope this helps.
