    Vibration disturbing the MAF connector? It looks like a complete signal dropout. Either the MAF internals are vibrating into a failure mode, or the connector is. That's my guess for why the signal would completely drop out like that at high RPM.

    Thanks for the reply... I'll take a look at that. I agree. I just wanted to be sure it wasn't a normal signal before I started searching.
