hi everyone. i have a vx ss and have a missfire under load. apparently crank angle sensor code keeps coming up. i have had the sensor replaced twice. leads, plugs, air flow meter have been done. i am only getting 11.3 volts coming from the ecu to the crank angle sensor, where there is supposed to be 12. I have had the ecu replaced to no prevail. my mechanic and myself are stuck any suggestions?
