I have owned a 2000 Accord EX V6 for about a year now. I have noticed that the speedometer is fast by about 5-7 mph at highway speeds. The tire size on the car are factory size (205-65 R15). I suspect that the revolutions setting in the computer have been changed for whatever reason in the cars history. It has about 120k miles on the car and I have not other problems with it.
Can someone tell me how to set the revolutions in the computer or speedo so I can check it or reset it, please?
