Cleaned MAF sensor and made sure no pins were bent. Checked main harness connections which were a little dirty so I hoped that was the issue but still no luck.

By the way, it will fire and run if I pour fuel in through a vacuum line attached to the intake. Unplugging the MAF sensor and MAP sensor do nothing.

Default Issue fixed on my wrx

This is what I have done to fix this issue.

Default I MIGHT have some helpful information on this topic.

Just created this account to create this reply. I have been a long time lurker and recently when thru something similar to the original question, sort of.

My 05 Wrx Wagon was having low rpm problems when i would shift out of gear into neutral, dropping below the 500's often and rising when it reached almost the very bottom, yet it wouldn't stall. It had this issue for a few months until recently did it start stalling completely when going out of gear and taking one or two startups to get it going again as it would die immediately after i would start it, only had to do the starting issue when the car would stall and it didn't always require more then one start up. My car never threw any codes for this.

I received both of these codes when i unplugged my MAF while my car was running and it shut off. I figure this means the MAF is doing its job? After this i decided to remove the intake, and thoroughly clean the throttle body, idle air control valve (IACV), and air filter. My IACV was filthy and gunky and i CAREFULLY cleaned it with throttle body cleaner and q-tips following a write-up i read here.

I apologize if some of this is not relevant but it may help someone in more than one way. Basically i believe anything with those codes will be related to a air problem. I read if you unplug it and the car keeps running that means its bad, but I'm not sure if its legible or not. Only other options would be a multimeter test, or connecting an OBD2 and creating a graph with the car running and i believe there is people in this forum that can see it and tell if its going bad. (EDIT) By the way in doing this all my issues went away and the car idles much nicely now, it always goes to the 1k rpm mark and slowly drops to the 500s.

I can post links to things relating to my issues if anyone needs them but again none of these relate directly to the problem the OP posted but i made them come up and feel this might help someone! Message me for any questions relating to issue and i might be able to help out i have learned quite a bit a long the way.

In my infinite stupidity, I learned that I had installed the MAF backwards which is what was causing my P0102 and P0113 codes. It was easily done with a home built CAI. Glad I figured it out but UGH!

Im gonna go ahead and bump this as well. Im getting both codes, as well as a P0037 P0112. Car runs and drives pretty well actually, makes boost just fine, and even idles fine when its warm. Has some delay in throttle though. However on startup, it idles kinda rough, and sounds like its backfiring a bit through the intake. These symptoms all go away as soon as I touch the throttle though, and it idles fine.

Went out and checked voltage on my maf connector. My wire colors are different for some reason, so these are listed from left to right, looking at the connector. What I get is the following

Key in on position, engine not on
YL---12v
BG---Ground
G----0v
LW---4.75
BR---Ground

Engine on
YL---12v
BG--Ground
G----1.62v
LW---3.95
BR---G

Really want this issue fixed, have a dyno day this friday...

EDIT: To make matters weirder, turned the car on, warmed it up, and erased the codes. now both these codes are gone... only have P0037, which I had before.
