Code 102001 air mass plausibility

Installed CTS intake a week ago. Then my car started to studder and turn off on cold start (only happens sometimes and when car sits overnight). Checked the coding, got a code of 102002 air mass plausibility.

Any ideas??

Did you make sure the MAF sensor as thr right orientation when you reinstalled it? Maybe its dirty and needs cleaned? I used this on mine https://www.amazon.com/Berryman-Prod...9151706&sr=8-3

Try putting the stock air box on and see if the problem goes away. Good luck!
