2004 Freelander P0171 System too lean x2

  

ToddinLou -> 2004 Freelander P0171 System too lean x2 (11/20/2007 3:46:56 PM)

Hey guys I'm looking for help. I had my 2004 Freelander to the dealer 2x already for fault code p0171 and its throwing the same code yet again. Last time they replaced an oxygen sensor under my extended warranty (last week) as well as the shift lock. Is this a common problem? Anyone have any other advice for things maybee I should check as I am getting really sick of seeing the guys at the dealership.

Thanks!!!

well this is what i was told. i have an 02 FL and it was throwing the same code. now i was told by the dealer that it was probably an o2 sensor. WRONG. i took it to my mechanic and he told me as well as showed me what the book said this code was. its the bank 1 sensor too lean. aka: a vacuum leak somewhere. now the most common place is the pcv valve. there is a small o-ring in there that goes bad and causes the leak. now mind you that is best case.  good luck and hope all is well for you.
