Sensor Help
 

Ok I have a new question. I installed my new crank sensor (the one directly behind the 30 degree mark on the timing cover) and the car still wont rev. I pulled both of the wires out of the connector and disconnected the white wire and the car killed. I started it back up and disconnected the black wire and the car reved up fine but as soon as I install the wire back on the sensor the idle started fluctuating again and the car wouldn't rev without sputtering like hell. Anyone have any idea what the hell is wrong with this thing? I only replaced one of the crank sensors.....The one directly behind the 30 degree timing mark.

Thanks
