Can anybody tell me what they think these MAF spikes are?? They are occurring at WOT. Thanks

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.
So I checked the wiring to the MAF and I can't cause a drop in the signal. I've included another pic of the drops, this time in steady cruise. I don't see anything else happening when the drops occur. I can include a log file if anybody wants to take a look.

Swap MAFs with a different one to rule out vibration affecting the MAF internals?

Yes that would do it... But I'll need to get one... hey wait what about just disconnecting it....????
