50 miles after I reseted my ecu due to head unit upgrade, I got this code. I already searched the forum and didn't really find a fix for it. Other forum members seemed to had an exhaust leak of some sort due to an after market set up, but I'm pretty much stock other than stillen gen3's.

So once I got home I deleted the code just incase it wouldn't pop up again. About 60 miles later the code showed up again. I jacked up the car to check the exhaust system and everything was good. Then check all vacuum lines, everything was good. Didn't check 02 sensors because this isn't the code for them so I checked my MAF sensors.

Took both MAF sensors out and cleaned them with CRC electrical cleaner and installed them. Since then I've put 200+ miles on the car with no problem. My guess is this might of fixed the problem. Hope this helps anyone else that might be fighting this code.
