P0171 and P0174 Codes intermittantly
What should I do? I want to spay nitrous, but do not want to do it with this thing telling me its running lean as it is.
The car runs fine. No power loss at any rpm range.
I dont get it .
Today I am going to check all PVC hoses and vacuum lines, etc, and maybe fuel pressure.
I did however find that the MAF wires were black from what I assume is air intake filter oil? So I cleaned the Intake filter, and the MAF wires, and they are as shiny as can be.
I also reset the Fuel tables and ECU so now we will see if these codes come back.
The car runs well though.
