My 1988 Olds 98 is giving me code 41 on the computer scan.  
  
 The car runs and drives fine, has always been meticulously maintained, and has only 43K original miles. I drive the car only on weekends – and occasional weekends at that. What repair is needed? Can an independent mechanic do this? Thanks

Can an independent mechanic work on this, or would I need the dealer? The car runs and drives fine, but the light bothers me.  
I want to make sure I take care of this car. Thanks

Any good shop can look into and work on the trouble. Since the car is running well I would think the cam sensor is ok.
