MAFS Question

First I'd like to say I'm just gonna blow up the dealership I bought the car from =). I got it in June, and since I got it, it's been stalling out every now and then at red lights and what not. I know it's a MAFS problem, because I took it to a mechanic and ran a diagnostics test. The thing that is confusing me is I've went through 3 MAFS and it's still messed up. Any other ideas on what it could be, other than the sensor itself? Thanks.

ur ECU probably ???
:dunno:

my friends cavalier did that ones because during the winter water went into the car on the passenger side and leaked into the ECU mounting area. and fried a couple of things, amazingly it still ran, but not very well.

:tongue:
