Are you sure that your odometer and speedometer are correct?....mine is off 20%, reading low - a mile only registers .8 miles on my odometer....my speedometer is also 20% off i.e. 75mph only registers 60 mph on my speedometer...the speed sensor has been changed, no change......sometimes when i disconnect the battery to clear the ECU (or pull the fuse) they reset and read correctly for a few days then go back to their 20% misreadings......just a thought
