Nissan Repair: elctricl brablim, crank angle sensor, optical unit

Question
wake spark

Answer
George,

I will assume the question is a weak spark.  You did not provide the year so I would assume the distributor if it has an optical unit is contaminated with oil on the optics and needs to be replaced.  Second, if it is only coil packs the crank angle sensor.  Check for codes and email me back with what you find.
