I am beyond pissed !!! I have taken my car back to the dealer four times because of Mass Air Sensor problems. The problem is that when my car idles the rpm's drop from 1000 to like 200 until it finally stalls. People might argue that it is because of the AEM CAI that I put on my car but, It started doing it before I even put it on and after I put it on. It has stopped doing it for about 2 months so I'll leave it at that. Nissan needs to get their ass working on a new and improved Mass Air Sensor or those after market companies. I hope NISMO makes a correctional part!!!!! !! Whenever they decide to get down to the U.S.
