Hi everyone i keep getting the p0171 code on my 2012 cruze here what i changed so far
turbo and gasket
intake manifold and gasket
valve cover
O2 sensor on bank 1
and it the code still comes on

A code P0171 may mean that one or more of the following has happened:

The MAF (Mass Air Flow) Sensor is dirty or faulty Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled.
There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
There could be a vacuum leak downstream of the MAF sensor
Possible cracked vacuum or PCV line/connection
Faulty or stuck open PCV valve
Failed or faulty oxygen sensor (bank 1, sensor 1)
Sticking/plugged or failed fuel injector
Low fuel pressure (possible plugged/dirty fuel filter!)
Exhaust leak between engine and first oxygen sensor

I checked the whole PVC system there’s no leaks or not in and there’s a good amount of gunk built up in there nozzle part of the intake where they orange nipple would be I’m pretty sure I can see the nipple still in there it’s just gunked up real bad

After you clean it off, keep an eye on it. If it is damaged in any way it will allow some bypass to occur. There have been occasions that the silicone hardens up as well.

Also must have gotten gunked up real bad because the hose that connects to it the check valve stuck open but I replace that hose with a new one but I’m wondering if it did damage to the intake isn’t that orange nipple like a check valve itself to I’m thinking with all the gunk that’s built up and it maybe I got stuck open or something

u mean clean it out? It’s the the little neck that sticks up from the intake. Has a orange nipple in it I guess… that’s what ur talking about right? And what would I use to clean it out?
