Spikes in MAF at WOT

[Motors]

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?

[Motors]

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

What would disconnecting it prove? We know there's a problem with the MAF, and it appears to be a signal dropout. If you disconnect the MAF, you'll just get signal dropout 100% of the time. That doesn't tell us why the signal is dropping out.

from what i see it seems taht MAF sensor is bad

Right I guess it would just be null. I was thinking if it were a wiring issue that the spike may remain. The MAF is only a year old and probably doesn’t have 300 miles on it.
