P0171 and P0174 Codes intermittantly
So every couple hours of drivin these two codes will come on for a bit, and then after a few more cycles will disappear. The car is stock except for a aftermarket intake filter. I have a 2004 Z06.
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 .

I havent touched the filter since I bought the car 7 months ago. it came with the filter. I do however notice that when I touch the inside of the filter, I get a decent amount of oil on my fingers.
Today I am going to check all PVC hoses and vacuum lines, etc, and maybe fuel pressure.

So update, I checked for PVC leaked and tightened all clamps down. No PVC leaks, no vacuum leaks, no leaks of any sort any where on the intake manifold. All clamps are tight for the air intake, and I have about 60psi of fuel pressure at the rail.
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.
