Code P1171

Hi Guys,

Any one know this code P1171. It only come on when I hard accelerator. This is for my Rodeo. Thanks.

Code p1171 for Isuzu is defined as, "Fuel System Lean During Acceleration".

Could be a bad or dirty MAF Sensor or a failing fuel pump.

In addition to the above, don't forget to inspect / replace the fuel filter.
