Message	The Technician did not really have any useful information. He wanted to blame one of the sensors or connections but I have checked and tested every one. He summed everything up by stating he would not know if it was the Eprom chip unless he had more information. Such as an A/F ratio graph from the wideband, and just about every sensors output signal for the whole rpm curve. This situation happened out of the blue and has not improved or worsen. There are no boost leaks.
