Im not sure where you are going with this????? I already said in a previous post that the car runs on all 6 cylinders when the sensor is unplugged, so logic would state that there is a problem with either the sensor, the harness plug, or the wiring harness itself, however I checked all of these items physically, so I think now that maybe the wiring is wrong at the ECU plug (which I have no idea how that could happen).
I bought the car in this condition, and the previous owner replaced almost every sensor on the car, as well as the ECU, but I dont know if he used the right ECU since there are so many that will physically plug in to this car.
Someone suggested that I reverse the wires at the wire harness that plugs into the crank pos. sensor. Would anyone recommend that or?????

Seems unbelievable equation. Like swapping spare tire would cause one cyl misfire...
ECU drives all injectors and coilpacks, It cannot select one or two not to function when pos or any other signal fails. Funny & loose or broken wiring: You must check all the wirings and wire color codes against FSM schema.
