PO 171 - check engine light

OBD II Code P0171 stands for Fuel System Too Lean (Bank 1). There is an article with good insights about this code here; http://repairpal.com/OBD-II-Code-P0171-and-P0174

too many things can cause this code, to list. Suggest you go to a Gold Shield station as you may be elidgible for cost repair assistance from the state. The state will not reimburse you for repairs made at other repair shops, so do not have any work done at a regular repair shop or dealership.

You have a vacuum leak. Check the engine over for yourself right now looking for any cracked or disconnected vacuum lines. Any leaks past the Mass Air Flow sensor (after the air cleaner) can set this code. If you can't find anything then stop by the shop and we'll take a look for you at NO charge. Good luck.
