I found a similar thread in the Diablo forum regarding fuel pump grounds, but before i go rooting around in there to clean grounds, has anyone had a similar issue? It was so quick and hard to describe, almost as if the pedal was no longer responding to me after i shifted from 3-4th gear. Besides the haptic feedback of "why isnt my body accelerating" the car maintained its current revs. Kinda freaky. I have a sprint booster installed, i double checked it to make sure it was seated properly and nothing was amiss there.
