SOLVED!!! RANGE ROVER 02 SENSOR FAULT CODE / FUEL SYSTEM TO LEAN CODE P0171 AND P0174
I couldn't believe that this would cause a fault code for the 02 sensors...but on my 2004 range rover hse 4.4l it sure did. i have been driving around for a month now and still the fault code hasn't come back...i spent over 6 months trying to figure this out. I threw lots of parts at this thing and still check engine light kept coming back after i reset it...now there is no back fire, no stalling and no fluctuation in the idle...hopefully this helps someone to save a little money..or maybe a lot of money...let me know if this does help you. leave me a comment in the section below...also check out the merch below to help support the channel. thanks for watching and we will see you on the next video!
