Hi, on the 1993 Buick Lesabre the crankshaft sensor is located under the dampener pulley. Remove the serpentine belt. Remove right front wheel. Remove plastic access cover thats behind that wheel. With an impact wrench remove dampener pulley bolt. With an Dampener pulley puller remove pulley. There is a plastic cover that snaps in place over the sensor, remove it, and you will have access to the sensor.

Well, we changed the oxygen sensor and my 1993 buick lesabre is still hesitating at times. The check engine light continues to come on...any clues now??? Could it be a fuel problem now....fuel filter or...

Sounds like this could be the mass air flow sensor.Have a local auto parts store diagnose the problem with their computer You could also have a bad throttle positioning sensor.
