Here's a good one...

I have a speed indication about 6 to 8 miles an hour too fast. The cruise control used to work, but no longer. I installed a new VSS. I know it works, because if I disconnect it and drive, there is no speed indication. I do have the proper size tires and wheels on this car as stated by the manufacturer. Any ideas?

 

problem may be in the cluster speedometer guage.
