Speedometer has been working intermittantly. Usually it won't begin working when I start the car but eventually come to life when it feels like it. Odometer didn't work at all. Cruise works just fine. I replaced the speedo and now it and the odo work fine. However my problem still remains where the speedo is always higher than the gps speed. Ie at 51mph the speedo says 62. At 35mph speedo say 40mph, so it looks like it has some fixed inconsistancy. I have the oem 15" tires on the car so I want to say that would rule out tires that are wrong. The car is an 1994 accord ex wagon.
