Running too Lean...P1131, P0171, P0174

[willik67]

My sons 96 3.0 started running a little rough and a little surging the other day. The codes that came up were P1131, P0171, P0174. Any help will be greatly appreciated.

Any help here? I have a similar issue, and plugs were a little whited too.\

I'm going to check Fuel Pressure.

oh thats a easy one, their are other things that could give a reading like that.

try looking at your pcv valve, these things will result in those readings, the hoses usually crack around them, it causes a vacuum leak and those are the readings you will get.

I'll check the PCV Valve and see if that helps
