P0102 Fault Code

My car has been stalling out on me when i slow down or stop at a red light. Sometimes while cruisng the car would shut off as well, the check engine light would come on. I finally decided to use a generic OBD II tool from autozone and came up with the code P0102 which indicates "Mass or Volume air flow A circuit low input"

Any fixes for this? I do have a AFE Intake on my BMW 325i.

Something to do with your MAF so I'd check the intake(boot)/hoses since you did change it. If don't find anything, clear the code and see if it comes back, if it does then you'll know you have to fix something.

Buy some MAF cleaner and check the intake/hose like mentioned above. I remember hearing that P0102 is a general fault code that can be related to a variety of issues but stalling at idle sounds like an air flow problem
