Hi guys just after some help. The engine management light is on and has been for a while iv had it plugged in and it brings up p0171system too lean bank 1 if you clear the code it comes back on in a short space of time the car drives perfectly well it doesnt affect it in anyway. just the fact that I want it right
iv done abit of research and found it could be maf sensor or o2 sensor dont want people guessing just wondered if some on here as had the same fault and cured it thanks guys !
