    Hi, I have a 2010 Mazda 3 and I have been trying to diagnose engine code P0171 for quite some time now, unfortunately without any luck. What I have tried so far: 1. I have checked for vacuum leaks using carburettor cleaner and there doesn't appear to be any 2. I have replaced the MAF sensor...

    Hello all, Took my 2016 Mazda 3 HB to dealership for this intermittent P0171 code. I took it to them for the 3rd time and they now recommended to replace the fuel injectors. The injectors are covered under warranty as the vehicle only has 35K miles. They also recommended to do engine carbon...

  7. Lean Code P0171 Popped & Hunted Down!

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    A few days back while driving up my hilly work route, my CEL lit w/o any symptoms. Having a Scangauge hooked fulltime gave me that privilege to instantly scan out the P0171 lean code. Knowing it wasn't serious & hoping t'was a fluke or random anomaly, I cleared it & carried on. I called the...
