my speedo lives on dope
My speedo has developed a weird problem. Sometimes when I stop at stoplights it is living it's own life - for example going crazy and showing that I'm doing 180km/h or so. After I start moving it goes back to normal. I'm not sure but it seems it is somehow connected to the brake pedal. Most of the time when I release it the strange behavior stops. Does anyone has idea what that might be? Couple of weeks ago I had gearbox rebuilt and the speedo sending unit gear was also changed. The unit itself is the same. Do you think that might be the cause of the problem? Car is '97 GTV 3.0V6, 5 speed.
