  Consumers 2005 isuzu npr sped up as if his foot was on the accelerator. ***No answer required*** *ts the consumer was unaware that the vehicle did not have an accelerator linkage like a conventional truck until after the fact. The truck was dependent on an electronic signal from the accelerator pedal in the cab to a computer to control the speed of the truck. the consumer believed the computer and accelerator control should be replaced on the truck, however no one was will willing to fix the vehicle, because it would have looked like an admission of guilt that there was a actually a mechanical problem. *jb
