2002 Explorer V8, SES Light & Too Lean Codes Dies, on idle

[Hansen317]

Hi,

I have a 2002 Explorer with a V8. The Service engine soon light is on. The engine runs but dies on idle when warm. The codes are P0171 System too lean (bank 1), P0174 System too lean (bank 2), P1131 Manufacturer Contrl. Fuel Air Metering & P1151 Manufacturer Contrl. Fuel Air Metering.

Does anyone have any idea what this could be caused by and how do I fix it?

I have some skills but not a mechanic. I have no special tools.

Any help would be appreciated.

The first thing I would do is check for vacuum leaks. Most likely the cause of the codes 171 and 174 will also be the reason for codes 1131 and 1151. Make sure the air inlet tube from the air filter to the throttle body is secure and has no rips or tears. Do you have a tool that can display the codes and data? I know you stated you have no special tools. What have you checked so far?

Since I know very little about this I haven't done anything other than take it to Autozone for a readout of the codes. I don't have the data reader tool.
