Here is that lean spike when not WOT. You can see everything is steady as can be when it happens. I have even hooked an oscope up to an injector, ran a jumper into the cab, and monitored the pulsewidths in real time. The injectors shut off for 300ms completely everytime this happens. I have also monitored voltage on the positive side of the injector plug, and it does not drop at all.

I am 100% sure this is related to the WOT spike, and 100% sure it is a computer related issue since I can see it stop commanding the injectors when it happens.
