the car does not go into limp . Drives terrific as usual. Check engine light triggers when I'm coasting down a grade. Is this a bad MAF sensor , or a slow leak in my charge piping somewhere, or some other sensor not working. Even though the car runs great I just hate the light on ( and no, I am not interested in taping a pic over the thing. Can someone tell me where to begin looking? Thanks

I'd have to go read it again... was Mass Air flow sensor/ control range not reached/ and it only occurs when I'm on a down grade throttle off in coasting
