Sign In I drive a 1997 Ford Contour. It is a little 4 banger engine with 140,000 miles on it. Recently it has been failing its state inspection. The code that it provides is: P0171 - Bank 1 System too lean. I've been given a diagnosis of everything from O2 sensor to a vacuum seal leak. If ANYONE knows what could be causing the problem and can give me a sure-fire solution, I would greatly appreciate it. I am tired of pouring money into this vehicle for it to NOT fix the problem. dmac0923 Enthusiast Oct 23, 2008, 5:35 AM Post #2 of 3 (1118 views) Re: Need immediate help! Sign In lean condition in bank 1 means the O2 sensor in bank 1 is detecting a lean condition (too much oxygen) check/clean your MAF sensor. check for any vaccuum leaks. __________________________________________________ 2015 Jeep Grand Cherokee 2002 Ford Ranger 2004 Toyota Corolla 1969 Ford Mustang Mach 1 way2old Veteran / Moderator Oct 23, 2008, 6:02 AM Post #3 of 3 (1116 views) Re: Need immediate help!
