Help, throttle override by the ECU (not due to riding the brakes)

[cossie1600]

In my attempt to fix my piece of $hit, it looks like my hesitation is actually my ECU snapping the throttle shut upon acceleration. It doesn't seem to happen often at WOT, but it just does it at random times. Obviously the harder I am on the gas, the harder it would cut. I don't know if the ECU is snapping completely shut or leaving a little open like the brake override the car has. I have tried to adjust the brake lamp and cruise brake switches, it doesn't seem to do anything. I have even tried to unplug it and pin it, still no help. Do you guys have any idea? I also get no check engine light since the car isn't misfiring, it is just closing the throttle on me even though I am asking for gas.

The only other symptom I have is that the cruise control would sometimes cut out on its own, but the shop manual on the forum doesn't have that section....
