I have an Olds 1990 Calais 4cyl Automatic tranny, and my speedo works
whenever it wants, I have a speedsensor in it and have tried to change it
and still not working. Also my Odometer and trip mweter do not work
either, sometimes it weill work and when it chooses to they all work at
the same time and when they stop its all of them at once. I really need
help please please please, this is my only car at the moment.....
