Doublevision... which engine do you have? and which type of sensor does it have? I was thinking it has the Hall effect sensor behind the balancer.
The permanent magnet sensor was an earlier style , that pushed in through the side of the block. Not sure at what production date they changed.
I have had both style crankshaft sensors cause a diveability problem like yours.
An ohmeter may or may not give a good indication of a defective Permanent magnet sensor , if it ohms out , it could still be bad, if it has a couple windings shorted to gether, amplitude of the sine wave( PM Generator) may be lower than threshhold voltage required and the signal generated can have a momentary "flat spot" or "glitch" that fails to signal or trigger the signal processor in the ICM /ECM
Ohming a hall effect type sensor is not recommended as usually wont give a good enough indication of health of the sensor.
A hall effect is designed to generate a square wave signal that can only be checked with an oscilliscope.
Fact is stranger than Fiction
