Woody,
Where did you get the BOSCH CPS? Of the three local stores (Kragen, Autozone, PepBoys), only Kragen had a CPS on their website, and it's part number CSS925 "BWD - Crankshaft Position Sensor". I'm not familiar with the BWD brand and would imagine that having a spare, especially from a reputable company like BOSCH, is a good idea.
