    Question HELP Vr code 56 error...

    hey ppls..

    ...Vr V6...just got an error code 56 Running Lean under Load
    Sensors or Circuits..havin trouble trying to understand by what it means by Running Lean under Load???

    Can it be a blockage in the fuel filter?
    Injectors are blocked?
    Blockage in the fuel lines?

    The car idles like its only firing on 2 cylinders and almost stalls, while driving along it shudders and if i have my foot flat on the pedal it drops back but only feel like i have the pedal halfway and it moves no-where

    sounds like fuel problem, could be regulator, fuel pump or could just be blocked fuel filter.

    Ive changed the filter, the car only seems to play up under a quarter of a tank..so i just keep it above that, maybe pressure or something?
