Happy New Year All!!! My car has been sitting in the driveway for the last coupe weeks during some weather and threw me a code P0171 "System too lean" one night when I started it up, it was about 22 degrees and snowing outside at the time. I shut it down and it sat for a week or so, I jumped it today since the battery died while the car was buried but the code remains. Anyone have any ideas as to what might cause this?

 

if the code reads L and R bank it could be a vacuum leak

 

My threw that code twice - as it turned out it was a bad tank of gas.

 

humm try so gasline anti freeze or a fuel stabil izer ?

 

I would first replace the fuel filter...
