I have a 2008 Mazda 6I -- L4 - 2.3L 2260cc - MFI GAS DOHC. I put in a cold air intake 5 years ago. It goes on and off with the car not being able to idle. It will stall out at stop signs and red lights. I do not have the original air intake assembly to put back on it. The stalling out is super annoying and I need to fix it. It's $90 to take it to the dealership just to look at it. I was thinking about replacing the mass air flow sensor to see if that corrects it. The check engine light is not on. Anyone seen this before or have any ideas?
